Bay of Islands,
New Zealand
"Where New Zealand was born — and where the sea still runs the day."
The Bay of Islands is New Zealand's founding landscape — a sub-tropical harbour of 144 islands where the Treaty of Waitangi was signed in 1840, where the country's first colonial town of Russell still stands on its far shore, and where dolphins, sailing, ancient kauri forests, and one of the world's great Pacific coastlines make the 3-hour drive from Auckland entirely worthwhile.
Where New Zealand Began
The Bay of Islands carries more history per square kilometre than anywhere else in New Zealand. This is where Kupe, the great Polynesian navigator, is said to have first set foot in Aotearoa. This is where the earliest European contact, trade, and settlement occurred in the late 18th century. And this is where, on 6 February 1840, over 500 Māori rangatira (chiefs) gathered with representatives of the British Crown to sign the Treaty of Waitangi — a document that defined the founding of New Zealand as a nation and whose interpretation continues to shape the country's laws and politics today.
But the Bay of Islands is not merely a museum of national history. The 144 islands scattered across its 800 square kilometres of sheltered water create one of the finest sailing and cruising grounds in the Southern Hemisphere. Common and bottlenose dolphins inhabit the bay year-round. The subtropical climate — warm, humid, pohutukawa-red in December — makes it one of the most pleasant environments in the country. And the town of Russell, reached by a 10-minute ferry from Paihia, is the finest historic townscape in New Zealand — barely changed since the 1840s.
Base yourself in Russell if you can — quieter, more atmospheric, and more genuinely historic than Paihia. Drive north for the extraordinary day trip to Cape Reinga, and west for the ancient kauri of Waipoua Forest. Two to three nights is the minimum; four to five allows the bay to be properly explored.
New Zealand's Most Important Site · 6 February
Waitangi Treaty Grounds — the Birthplace of a Nation
The Waitangi Treaty Grounds are the most historically and politically significant site in New Zealand — the place where the Treaty was signed in 1840, where the relationship between Māori and the Crown was defined, and where that relationship continues to be debated, celebrated, and renegotiated today.

Waitangi — where New Zealand was made
The Waitangi Treaty Grounds cover 506 acres of headland overlooking the Bay of Islands — the setting of the signing on 6 February 1840. The experience begins with a guided tour of the Treaty House (1834, the oldest surviving building in Northland, home of British Resident James Busby who helped draft the Treaty), the adjacent carved wharenui (Te Whare Rūnanga, 1940), and the 35-metre waka taua (war canoe), one of the largest in New Zealand, housed in its own purpose-built canoe house on the waterfront. The daily cultural performance — a 75-minute programme of haka, waiata, poi, and a dramatic re-enactment of the Treaty signing — is one of the most powerful publicly available cultural experiences in New Zealand. The viewing deck over the Treaty House lawn, where the original signing took place, is extraordinary to stand on. On Waitangi Day itself (6 February, a national public holiday), the grounds become the stage for both formal government commemoration and significant Māori protest — a powerful, contested, living history.
Kerikeri Mission Station
The Kemp House at Kerikeri (1822) is New Zealand's oldest surviving European building — a Georgian cottage that housed the earliest Anglican missionaries at the edge of the Kerikeri River inlet. The adjacent Stone Store (1836) is the oldest stone building in New Zealand. Both are Heritage NZ properties with guided tours. The mission station sits in a remarkably preserved setting: the stone store, the mission house, and the river beyond create a scene that has barely changed in 200 years. Kerikeri township itself has an excellent farmers market (Sunday mornings) and several good café and restaurant options.
Te Kongahu Museum of Waitangi
The purpose-built museum at the Waitangi Treaty Grounds (opened 2016) tells the full story of the Treaty of Waitangi and its impact on New Zealand with an honesty and depth that previous presentations avoided. The collection includes original Treaty documents, taonga (treasures), and contemporary Māori art responding to the Treaty and its contested legacy. Admission to the museum is included in the Waitangi Treaty Grounds ticket. Allow 1.5 hours. Essential context for understanding modern New Zealand.
The Treaty Pohutukawa
On the waterfront at the Waitangi Treaty Grounds stands a massive pohutukawa tree (Metrosideros excelsa) believed to be over 1,000 years old — one of the largest in New Zealand, with an enormous spreading canopy. According to Māori tradition, this tree marks the place where the spirit of the dead departs for Hawaiki, ascending to the sky. The tree was present when the Treaty was signed, 185 years ago. Its presence beneath the Treaty House lawn connects the living culture of the signing to the deep pre-European history of the bay.
Catamaran Cruise · Dolphins · 144 Islands
Hole in the Rock — through the Bay
The Hole in the Rock cruise is the Bay of Islands' signature experience — a 4-hour catamaran journey through 144 scattered islands to the natural arch at Piercy Island, almost always encountering dolphins, seabirds, and the wild open Pacific beyond the bay's entrance.
Piercy Island · Motukōkako · Fullers GreatSights
Piercy Island — the Arch at Land's End
The Hole in the Rock cruise departs from Paihia Wharf and navigates through the sheltered inner bay — past Russell, Urupukapuka Island, and the scattering of islets and headlands that give the bay its character — before emerging through the Cape Brett Peninsula into the open Pacific, where Piercy Island (Motukōkako) stands as a 46-metre sea stack with a 15-metre natural arch bored through its base by 10,000 years of Pacific swell. The catamaran navigates through the arch in calm conditions (a skilled piece of seamanship) to complete one of the most dramatic singular moments in New Zealand tourism. The dolphins are the other constant — common dolphins in pods of up to 500, leaping the bow wave throughout the outer bay passage, are among the most joyful wildlife encounters available anywhere in New Zealand. Fullers GreatSights' "Cream Trip" (5 hours, daily) follows the historic route of the mail boat, stopping at island homesteads — a slower and more local experience of the bay than the direct Hole in the Rock cruise.

Russell — New Zealand's Oldest Town
Russell (originally Kororāreka — "how sweet is the penguin" in Māori, a reference to the blue penguins that once nested on the foreshore) is the oldest surviving European settlement in New Zealand — accessible only by a 10-minute ferry from Paihia and almost entirely unchanged from its Victorian-era streetscape.

Russell · Kororāreka · NZ's Founding Town
Russell — the Town That Shaped New Zealand
Russell is the most historically dense settlement in New Zealand — a town of perhaps 900 permanent residents that holds more significant buildings per street than any other place in the country. The Duke of Marlborough Hotel (1827, continuously licensed since — the oldest licensed hotel licence in New Zealand) anchors the waterfront. Christ Church (1836), New Zealand's oldest surviving church, still shows musket balls in its walls from the 1845 battle when Hone Heke and Kawiti attacked Kororāreka. Pompallier Mission (1842) — the only surviving industrial building from early New Zealand, built to house the Catholic press — is a Heritage NZ site with guided tours. The Russell Museum tells the complete story of the town and the early contact period. Walk the flat waterfront street from the ferry wharf to Pompallier and back in 90 minutes; take the longer hill walk to the flagstaff (where Hone Heke felled the pole four times) for the finest view of the bay. Stay overnight — Russell at dusk, with yachts on their moorings and the light going golden over the water, is one of the finest evening scenes in New Zealand.
Russell vs Paihia — Where to Stay
The choice between Russell and Paihia defines the Bay of Islands experience. Russell is quieter, more atmospheric, more authentically historic, and further from the worst of the tourist infrastructure — but requires the ferry for all cruises and the main Paihia visitor facilities. Paihia is more convenient for the Hole in the Rock and Waitangi, louder, and has more accommodation range. For visitors staying 3+ nights: Russell. For day-trippers or one-night stops: Paihia. The best accommodation in the bay is in Russell — the Duke of Marlborough Hotel, Hananui Lodge, and the Russell Top 10 Holiday Park on the hill are all excellent.
The Rainbow Warrior Wreck
One of New Zealand's most significant dive sites — the Greenpeace flagship Rainbow Warrior, sunk by French intelligence agents in Auckland Harbour in 1985, was refloated and scuttled at Matauri Bay near Cavalli Islands (45 min from Paihia) in 1987. The wreck sits at 27 metres on a sand and shell bottom surrounded by coral and schooling fish. Paihia Dive and other operators run regular trips; the wreck is considered one of the finest recreational dives in the North Island. The site is deeply symbolic in New Zealand's anti-nuclear history.
Game Fishing
The Bay of Islands has been one of New Zealand's premier game fishing grounds since the 1920s — Zane Grey fished here in 1926 and wrote about it extensively, putting the bay on the global sport-fishing map. Black and striped marlin (November–April), yellowfin tuna, kingfish, and mahi-mahi are the primary targets. The Bay of Islands Swordfish Club at Russell (1929) is one of the world's oldest big-game fishing clubs and maintains records going back nearly a century. Charter boats operate from both Paihia and Russell; half-day and full-day options available.
Common & Bottlenose · Year-Round · Bay & Open Pacific
Dolphins & Marine Wildlife
The Bay of Islands has one of the highest and most consistent densities of wild dolphins in New Zealand — common dolphins (in pods of up to 500) and bottlenose dolphins inhabit the bay year-round, with encounters virtually guaranteed on any cruise departing into the outer bay.
Fullers GreatSights · Explore NZ · Oct–Apr Best
Swimming with Wild Dolphins
The "Swim with the Dolphins" experience offered by Fullers GreatSights and Explore NZ is one of the most extraordinary wildlife encounters available in New Zealand — a guided open-water swim alongside wild common or bottlenose dolphins in the outer bay. The boat crew locates dolphin pods in the bay (typically within 20 minutes of departure from Paihia) and deploys snorkellers ahead of the pod's direction of travel; the dolphins approach at their own choice, swimming alongside and beneath the snorkellers in water of 15–22°C clarity. The experience is entirely dependent on dolphin behaviour — they are wild animals and are not attracted, fed, or coerced. October to April produces the most consistent encounters as dolphin pods are largest and most active near the surface in warmer water. Full wetsuits and snorkelling equipment are provided. No experience required; swimming confidence essential.
Wild common & bottlenose dolphins · year-round
Whale Watching
Orca (killer whales) pass through the Bay of Islands and Northland coast on seasonal migrations — winter months (May–September) are most productive for orca sightings, particularly around the Cavalli Islands and in the open waters off Cape Brett. Humpback and southern right whales occasionally transit Northland waters in winter. Whale watching is not guaranteed and no dedicated whale-watch operators exist in the Bay of Islands — sightings occur as a bonus on dolphin and fishing charters rather than as the primary purpose of a trip.
Poor Knights Islands Diving
Two hours south of the Bay of Islands near Tutukaka (1.5 hrs from Paihia) — the Poor Knights Islands marine reserve is consistently rated one of the world's top dive sites. Volcanic sea arches, caves, and tunnels with extraordinary visibility (20–40 m) and subtropical marine species including three species of seahorse, manta rays, and schooling fish in enormous numbers. Jacques Cousteau rated it among the world's top ten dive sites. Day trips from Tutukaka with Dive! Tutukaka; also accessible from Paihia with a longer drive.
Sea Kayaking the Bay
The Bay of Islands is one of New Zealand's finest sea kayaking environments — the sheltered inner harbour (between Paihia, Russell, and the near islands) is calm enough for beginner paddlers, while the outer bay and Cape Brett area offer more challenging conditions for experienced kayakers. Bay of Islands Kayak (based Paihia) offers guided half-day and full-day tours to the inner islands; self-guided hire available for experienced paddlers. Camping on Urupukapuka Island (DOC campsites) with kayaks for 2–3 days is one of the great low-key Bay of Islands experiences.

Cape Reinga — where the Seas Meet
Cape Reinga (Te Rerenga Wairua — "the leaping off place of spirits") is New Zealand's northernmost accessible point and one of the most spiritually significant places in Māori cosmology — the place where souls of the dead leave Aotearoa to travel back to Hawaiki.

Cape Reinga · 5 hrs from Paihia · Northland's Far North
Cape Reinga — the Top of New Zealand
Cape Reinga is 225 km north of Paihia and takes approximately 5 hours to reach by road — but the drive through the Far North, past ancient kauri forests, along spectacular Ninety Mile Beach (accessible by 4WD or by tour bus), and through the small towns of Kaitaia and Awanui, is as much the experience as the destination. At the Cape itself, a 500-year-old pōhutukawa tree clings to the cliff edge above the sea — according to Māori tradition, the spirits of the dead descend its roots, swim to Te Reinga (Three Kings Islands beyond the horizon), and depart for Hawaiki. The lighthouse (1941) stands above the point where the Tasman Sea and the Pacific Ocean collide in a visible, turbulent meeting line — you can see both bodies of water simultaneously on a clear day. The entire Far North is deeply sacred to Ngāti Kuri, Te Aupōuri, and Ngāi Takoto — please treat the area with cultural respect. Note: Ninety Mile Beach should only be driven on a tour bus, not in a hire car (rental car warranties are void on the beach, and incoming tides trap vehicles regularly).
Northland's Far North · 88 km Beach
Ninety Mile Beach — the Long Road North
Ninety Mile Beach (actually 88 km long — a surveying error by early European settlers persists in the name) runs along Northland's west coast from Ahipara in the south to Scott Point near Cape Reinga. The beach is a legal road in New Zealand (gazetted as a public highway in 1936), which has resulted in the famous spectacle of tour buses driving its length — stopping to sandboard down Te Paki Dunes (the massive sand dunes where the beach meets the Cape Reinga road), to swim in the surf, and to cut giant surf clams (tuatua) from the sand at low tide and cook them on site. The sand clams are a highlight — sweet, fresh, and eaten within minutes of harvest. All Cape Reinga day tours from Paihia include the beach leg and the dunes; most return via the sealed Inland road, making it a one-way beach experience.

Waipoua Kauri Forest — the Lord of the Forest
Waipoua Forest on Northland's west coast is the largest surviving kauri forest in New Zealand — home to Tāne Mahuta, the most sacred kauri tree in existence, standing 51 metres tall and over 2,000 years old. One of the most extraordinary encounters with a living thing available anywhere.

Tāne Mahuta — Lord of the Forest
Tāne Mahuta — "God of the Forest" in Māori cosmology — is the largest known living kauri tree in New Zealand. Its vital statistics are extraordinary: 51.5 metres tall, trunk girth of 13.77 metres, estimated age of 1,250–2,500 years depending on the method of estimation. A 10-minute walk from the road through secondary kauri forest brings you to the tree; the first view of it — a single vast trunk rising into the canopy above, with a crown spread of 20 metres — is genuinely shocking in scale. Te Matua Ngahere ("Father of the Forest"), a shorter but considerably wider tree 45 minutes deeper in the forest, has an even larger trunk girth (16.41 m) and is estimated to be older. Both are sacred to the Ngāti Whātua, Te Uri o Hau, and Ngāpuhi. The forest is under active threat from Phytophthora agathidicida (kauri dieback) — washing and drying stations are located at all track entrances. This is mandatory, not optional. Please treat it as such.

Sailing & Watersports
The Bay of Islands is one of the finest sailing grounds in the Southern Hemisphere — 144 islands in a sheltered harbour, consistent summer winds, and anchorages ranging from busy waterfront bays to deserted beach coves. The Bay of Islands Sailing Week (January) is a highlight of the New Zealand sailing calendar.
Charter Sailing
The Bay of Islands has one of the finest bareboat charter fleets in New Zealand — sail to deserted island anchorages, snorkel from the boat, and spend the night anchored off Urupukapuka or Otehei Bay with the islands to yourself. Crewed charters (the skippered experience with no sailing knowledge required) range from a half-day sail to a multi-day island-hopping voyage. Explore NZ, Salt Air, and Carino Sailing run crewed day sails; Moorings NZ operates the bareboat fleet from Opua Marina.
Bay Action & Adventure
Paihia is the Bay of Islands' activity hub for water-based adventure — parasailing (views across the 144 islands from 200 m while towed behind a boat), jet ski hire (self-guided tours around the inner bay), wakeboarding, and tube rides are all available from the Paihia waterfront operators. Bay of Islands Parasailing has operated since 1986 and is the most established. The jet ski hire gives self-guided freedom to explore the near islands, caves, and beach coves at your own pace — a 2-hour hire covers significant ground.
Light Tackle & Shore Fishing
Beyond the game fishing, the Bay of Islands offers excellent light-tackle fishing year-round — snapper are the primary target, schooling around the island reef edges and in the harbour mouth in catches of genuine size (50+ cm fish are common). Kingfish (yellowtail kingfish) to 20+ kg are caught trolling the outer bay May–October. Kayak fishing from Russell or Paihia using hire kayaks with light gear is an increasingly popular self-guided option. The inner harbour rocks at dusk are productive for snapper with bait; Paihia sports shops sell day licences and gear.
144 Islands · Walking · Swimming · Camping
The Islands
The 144 islands of the Bay of Islands range from busy day-trip destinations with cafés and walking tracks to remote uninhabited islets accessible only by private boat. Several are DOC-administered with free camping.
The bay's largest island with 10 km of walking tracks, three DOC campsites, and the historic Zane Grey fishing lodge at Otehei Bay (now a café and backpacker lodge). Accessible by Hole in the Rock cruise or water taxi from Paihia and Russell. The 1.5-hr Urupukapuka Ridge Walk has the finest views of the bay's island scatter.
A pest-free island sanctuary 20 minutes by water taxi from Paihia — home to kiwi, weka, and rare native birds reintroduced since rat eradication. The circular walk (3 hrs) gives panoramic bay views. No camping; day visits only via water taxi. The contrast between the living bird sounds on Moturua and the relative silence of the pest-affected mainland is striking.
A figure-8 island with two sheltered lagoons popular for swimming and snorkelling on calm days. No facilities; access by charter boat or water taxi from Paihia or Russell. The underwater visibility in the lagoons on calm days is excellent. The ridge walk between the two bays gives good views of the inner harbour and the Cape Brett Peninsula beyond.
The 46-metre sea stack at the bay's Pacific entrance through which the Hole in the Rock cruise navigates — one of the most dramatic geological features in Northland. Seabirds including Australasian gannets and the endemic New Zealand king shag nest on the stack's ledges. Not accessible for landing; viewed only from the cruise.
A smaller, less-visited island in the north-western bay accessible by private boat or kayak — favoured by local sailors for its secluded anchorage and clear water. The island's pohutukawa trees bloom red in December, making it particularly beautiful in early summer when the Christmas tree is at full colour against the Pacific blue.
45 minutes north of Paihia — the Cavalli Islands are a group of rugged offshore islands at the start of Northland's most remote coastline. The Rainbow Warrior wreck lies at 27 metres in Matauri Bay, accessible by dive charter. Matauri Bay township itself has a memorial to the Rainbow Warrior and an excellent surf beach at the bay's southern end.
December · The NZ Christmas Tree
The Pohutukawa Season
The pohutukawa (Metrosideros excelsa) is the defining tree of Northland's coastline — an ancient, gnarled, spreading tree that drapes itself over cliff edges and beaches throughout the Bay of Islands, and bursts into brilliant crimson flower in late November and December. The flowering coincides with New Zealand's Christmas and the beginning of summer: Northland's pohutukawa bloom is one of the most spectacular natural events in the country.
The Bay of Islands is one of the finest places in New Zealand to see pohutukawa — the trees line the Russell waterfront, hang over the Paihia beach, droop from the cliffs above Cape Brett, and scatter across every island in the bay. At Waitangi Treaty Grounds, the 1,000-year-old pohutukawa at the waterfront edge carries both the deepest cultural meaning and one of the finest crimson flower displays in the region. Come in December for maximum colour impact.
Subtropical Climate · Year-Round Destination
When to Visit the Bay of Islands
The Bay of Islands has a warm sub-tropical climate — the warmest and most reliably sunny region in New Zealand. It is genuinely pleasant in every season, though summer brings the crowds and winter brings the tranquillity.
Peak season — warm sea temperatures (22°C) ideal for dolphin swimming, sailing, and island visits. Pohutukawa trees in full red flower (December). Bay of Islands Sailing Week (January). Busiest and most expensive; Russell fills completely in the Christmas–New Year period. Book accommodation months ahead.
The finest season for most visitors — sea still warm from summer, crowds diminishing from March, and settled weather conditions ideal for sailing, diving, and the Cape Reinga day trip. Game fishing (marlin, yellowfin) in full season March–April. Fewer people at Waitangi; the Treaty Grounds are best experienced without summer crowds.
Mild and uncrowded — Bay of Islands winter rarely drops below 10°C and the Hole in the Rock cruise, Waitangi, and Russell all operate year-round. Orca (killer whales) are most likely June–August as they follow stingray and snapper southward. Lowest accommodation prices of the year. The bay in winter light is extraordinarily beautiful and receives very few international visitors.
Warming rapidly from September — game fishing season begins October (marlin arrive November); the bay is at its greenest and the bush pohutukawa are in bud by November. Good conditions for Cape Reinga with stable weather and longer days. September is the start of the school year in NZ — accommodation prices drop significantly after February.
Getting There & Getting Around
Planning Your Bay of Islands Trip
Getting to the Bay of Islands
- Driving from Auckland: 245 km via State Highway 1 through Whangarei — approximately 3 hours in normal conditions (allow 3.5 hrs with a coffee stop). The route is sealed and well-maintained throughout
- Stop en route: Whangarei Falls (20 min off SH1, free) — a 26-metre urban waterfall dropping into a native bush gorge, one of NZ's most accessible waterfalls; and Tutukaka (for those adding a Poor Knights Islands dive)
- InterCity buses connect Auckland to Paihia daily — the journey takes approximately 4 hours; buses stop at Whangarei and Kawakawa (the Hundertwasser toilet town) en route. Book at intercity.co.nz
- Kerikeri Airport has direct Air New Zealand flights from Auckland (40 min) — limited schedule but allows a car-free option with vehicle hire from the airport
- No direct train service from Auckland — the Northland rail corridor was discontinued; bus is the only public transport option
Getting Around
- The passenger ferry between Paihia and Russell (Black Rock) runs every 20–30 minutes 7am–10pm daily — NZ$8 each way; 10-minute crossing; no booking required. This is the primary transport link for Russell visitors
- The Opua car ferry (10 km south of Paihia) connects to Okiato for those needing to take a vehicle to Russell — departs every 10 minutes; NZ$14 per vehicle including driver
- Water taxis between Paihia, Russell, and the islands: Paihia Water Taxis and Bay of Islands Water Taxis operate year-round; book by phone or from the Paihia waterfront. Typical island fares: NZ$25–40 return per person
- Car hire: several companies operate from Paihia and Kerikeri; essential for the Cape Reinga drive, Waipoua Forest, and exploring beyond the bay townships
- Paihia is walkable: the Paihia waterfront, Waitangi Treaty Grounds (15-min walk from Paihia Wharf), and all cruise operators are within easy walking distance of each other
Cultural Respect & Practicalities
- The Bay of Islands is deeply significant to Ngāpuhi — the largest iwi (tribe) in New Zealand, whose rohe (tribal area) covers all of Northland. The Treaty of Waitangi was signed primarily with Ngāpuhi rangatira
- At the Waitangi Treaty Grounds, follow all guide instructions; photography is generally permitted except where signposted; respect the sacred wharenui and Treaty House interiors
- Cape Reinga is a very sacred site — no swimming, fishing, or eating at the cape itself; respect all signage about cultural protocols; the cape's significance to Māori is profound and predates any tourist activity
- Kauri dieback disease: wash and dry footwear at ALL Waipoua Forest wash stations — this is not optional; the disease has no cure and has already destroyed kauri across significant parts of Northland
- Ninety Mile Beach: never drive a hire car on the beach — rental car insurance is void and tidal trapping is a regular occurrence. Tour buses only
- Accommodation: book at least 6 months ahead for Christmas–New Year period in Russell and Paihia; the bay fills completely and last-minute rooms are not available at any price
Common Questions
Bay of Islands FAQs
The Bay of Islands is approximately 245 km north of Auckland — around 3 hours by car via State Highway 1 through Whangarei. The route is entirely sealed and well-maintained. Worth stopping at Whangarei Falls (20 minutes off the main road) en route. InterCity buses connect Auckland to Paihia daily in approximately 4 hours. There is no direct train service. Kerikeri Airport has direct Air New Zealand flights from Auckland (40 minutes) with hire cars available.
The Hole in the Rock cruise is a catamaran tour from Paihia Wharf navigating through the 144 islands to the natural rock arch at Piercy Island (Motukōkako) — a 15-metre hole bored through a 46-metre sea stack at the bay's Pacific entrance. The cruise takes approximately 4 hours return and almost always encounters common or bottlenose dolphins in the outer bay. In calm conditions, the catamaran navigates through the arch itself. Fullers GreatSights operates the most established service from Paihia Wharf; departures are daily year-round. Book online at fullers.co.nz.
The easiest way is the passenger ferry from Paihia Wharf to Russell — it runs every 20–30 minutes from 7am to 10pm daily; the crossing takes 10 minutes and costs NZ$8 each way. No booking required; just turn up. For those who need to take a car to Russell, a car ferry operates from Opua (10 km south of Paihia) to Okiato — departing every 10 minutes during the day, NZ$14 per vehicle. For most visitors, the passenger ferry is the correct choice — Russell is best explored on foot.
The Bay of Islands is genuinely pleasant year-round in its subtropical climate. Summer (December–February) is warmest for swimming and dolphin encounters, with the pohutukawa in bloom, but brings the largest crowds and highest prices — book accommodation 6 months ahead for Christmas–New Year. Autumn (March–May) is excellent — warm sea, smaller crowds, and good game fishing. Winter (June–August) is mild, uncrowded, and the best time for orca sightings; accommodation prices drop significantly. Spring (September–November) sees the bay warm up with good value and the game fishing season opening in October.
