Kaikoura whale and dolphin watching can mean one boat or two: dusky dolphins in their hundreds, the choice between swimming and watching, and how to pair them with the sperm whales.

Kaikoura dolphin watching: meet the dusky dolphins

Kaikoura dolphin watching mostly means dusky dolphins. The Department of Conservation describes groups from several hundred to over 1000 animals present off Kaikoura all year round.1 They are compact, quick dolphins: females reach 1.93 m and males 2.11 m at most.6 When a big group is travelling and leaping, the sea seems to boil. Watch for the high, spinning leaps and the belly flops that land with a slap you can hear from the deck, a show that does not get old however many times you see it.

They work the night shift. In Kaikoura dusky dolphins feed mostly at night, on prey that rises with the deep scattering layer.7 In daylight they rest, socialise and play, which is when boats find them. Calves are born from November to mid-January, and the youngest stay tight against their mothers.8

The dolphins move with the seasons. From October to May they come inshore each early morning to the south side of the Kaikoura Peninsula.2 From June to September they stay further offshore and range over a wider stretch of coast.9 In practice a summer trip may find them near town, a winter trip may have to travel further.

As the operators state them; every trip depends on the weather and the animals on the day.26

Seeing dolphins on the whale cruise

You do not need a separate trip to see dolphins. The whale operator lists dusky dolphin pods among the animals a typical cruise may meet, with fur seals and the wandering albatross.5 With the whales seen and minutes to spare, the boat may track closer to the shoreline in search of dolphins and seals.17

There is one limit to know about. From November to March a Department of Conservation rest period applies: no vessel may watch dusky dolphins from 11.30am to 1.30pm.18 If seeing dolphins from the whale boat matters to you in summer, a morning or late afternoon sailing gives the captain more room.

Other dolphins live here too. Hector's dolphins are found only in New Zealand's coastal waters, and around Kaikoura they keep close to the beaches.19 Orca pass through during the year, particularly from September to April, and the dolphin operator calls them a chance encounter.20

Ages that matter

Kaikoura whale watching and dolphin swimming

The bolder option is not watching the dolphins but swimming with them. Dolphin Encounter leaves from 96 Esplanade, a 5-minute stroll from the middle of town.28 Its trip lasts about 4 hours from check-in, with about 2.5 hours at sea.11 Swimmers and watchers share the same boat, and a family can split between the water and the deck.29

In the water you are close. Swimmers are usually about an arm's length from the dolphins, and with an interactive group the swim averages 20-30 minutes.27,12 The crew stay on board, and you need enough upper body strength to climb back onto the boat without help.30,31 Department of Conservation permits cap each boat at 16 swimmers per tour.32

The sea is cold. It rarely passes 18 °C in summer and drops to about 9 °C in winter.13 Swimmers get a 5mm one-piece wetsuit and a 5mm jacket at base, plus a hood, mask, snorkel and fins.33,34 Prescription masks are available for short-sighted swimmers, but full face snorkel masks are not allowed.35,36

Ages, pregnancy and who can swim

Age rules differ between the boats. The whale cruise takes children from 3 years.21 Dolphin Encounter also takes nobody under 3, and swimmers must be at least 8; children aged 8 to 14 need an adult beside them in the water and on board.4,3

Pregnancy has its own limits on the dolphin boat. Swimmers must be under 30 weeks pregnant, and watchers under 34 weeks, or 32 weeks for a multiple pregnancy.42,43 The operator adds that pregnancy can raise the risk of seasickness.44 On the whale boat, the captain may restrict pregnant passengers when the sea is rough.45

Access is limited too. The dolphin operator generally cannot take wheelchairs on board.46 The whale boat can take wheelchair users when the sea is calm enough, subject to the captain's call on the day.47 For travellers with limited mobility, the whale cruise is the more practical of the trips.

Rules that protect the dolphins

Dusky dolphins are watched closely here. The Department of Conservation says its management of the species focuses on the impact of tourism at Kaikoura.48 Swimmer numbers and dolphin rest periods are set by permit and by the Department, not left to each operator.32,18

The general rules apply to everyone on the water. Do not swim with dolphin pods that include juveniles.38 Boats and aircraft together may number no more than 3 within 300 m of a group.49 Every dolphin in New Zealand is protected under the Marine Mammals Protection Act 1978.50

What this means for you: on some days a skipper will pull swimmers out early, or keep everyone on deck. It can feel like a loss in the moment, but it is the system doing its job, and the dolphins that are left alone today are the ones that come back to the boats tomorrow. Dolphin Encounter refunds swimmers down to the watcher rate when a swim is not possible but dolphins are seen.51

Before a dolphin swim

What is provided and what to sort out

Provided3

  • A 5mm wetsuit and jacket33
  • Hood, mask, snorkel and fins34
  • Prescription masks on request35

Not allowed3

  • Full face snorkel masks36
  • Drones without a DOC permit37
  • Swimming with pods that include juveniles38

Plan ahead3

  • Book early: summer swims sell out39
  • Change or cancel 24 hours ahead at the latest40
  • Seasickness tablets before you board41

Fitting whales and dolphins into one day

Doing both in a day is common, and the order matters. Dolphin Encounter recommends its morning departures, when the sea is often calmer and the dolphins livelier.10 The whale boats leave at 7.45am, at 10.30am and at 13.15 in every season, with an extra 16.00 departure in the November to March summer.15 A dolphin trip early and the whale cruise in the afternoon is the natural pairing.

Allow real gaps. The dolphin trip takes about 4 hours from check-in, and the whale cruise needs 3 hours and 15 minutes including its own check-in.11,16 You will want a hot shower and lunch between them, and a dry set of clothes for the second boat, since a wetsuit leaves you chilled long after you climb out. Both trips are open-ocean outings, and taking seasickness tablets before each one is wise.41,52

Book both early in summer. The dolphin swim often sells out in the warmer months.39 The whale operator also advises booking well ahead.53 If you want a second dolphin trip, Dolphin Encounter gives 20% off a second tour within a year, and 15% off for groups of 4 or more.54,55

Day tours from Christchurch with dolphins

Without a car, a guided day is the easy route. A swim with dolphins day tour from Christchurch lasts 12 hours, takes up to 16 people and starts from $283 on Viator. Read the terms before you pay: that listing is non-refundable.

A second day tour on GetYourGuide includes a dolphin encounter. It runs 10 hours from $240, with free cancellation until 24 hours ahead. Its plan lists 1 hour of free time and a 30-minute lunch in Kaikoura, then 4 hours of dolphin watching.

If whales matter more than dolphins, the whale day tour from Christchurch is the better buy, and the cruise often meets dolphins on the way.5 Whichever you choose, the refund rules differ: the whale boat refunds 80% if no whale is seen, and the dolphin boat gives a partial refund if no dolphins are found.24,25
