Kelly Tarlton's Sea Life Aquarium Auckland — visitor guide

Kelly Tarlton’s: the aquarium in the old sewage tanks

Kelly Tarlton’s Sea Life Aquarium in Auckland has a genuinely unusual origin story. The aquarium — built by New Zealand diving pioneer Kelly Tarlton in 1985 — is housed in the old Hobson Bay sewage storage tanks below the Mission Bay waterfront. The circular concrete tanks, which were decommissioned in 1983, provided the infrastructure for what became the first walk-through aquarium tunnel in the world (preceding the more famous facilities in Japan and Europe by several years).

Kelly Tarlton’s vision — a curved acrylic tunnel through which visitors move on a travellator while sharks and rays swim overhead — was genuinely revolutionary. The original Tarlton (who died of a heart attack just 6 weeks after opening, at age 47) never saw how influential the concept would become. The Merlin Entertainments / SEA LIFE brand acquired the aquarium in the 1990s and has invested significantly in the Antarctic and other newer exhibits.

The aquarium’s position in old sewage tanks is not as grotesque as it sounds — the circular concrete vaults have been fully lined and fitted. But it does mean that the layout is unusual: a series of connected domed chambers and tunnels rather than a conventional rectangular aquarium building.

The Antarctic exhibit: the standout

The Antarctic World exhibit at Kelly Tarlton’s is the most significant component of the aquarium and the one that most distinguishes it from comparable attractions globally.

The penguin colony: Live Gentoo and King penguins in an Antarctic-replica environment — artificially chilled to -2°C, with a snow machine, authentic-looking ice formations, and deep (1.5m+) swimming pools designed to allow the penguins to exhibit natural diving and swimming behaviour. The Gentoo penguins (smaller, faster swimmers — capable of reaching 36km/h in water) and the King penguins (the second-largest penguin species, with the characteristic golden breast marking) are the same species managed by Antarctic conservation programmes globally.

Visitors walk through the exhibit in a climate-controlled passage that gives views of both the above-ice living area and the underwater swimming through transparent panels. A revolving tour (a motorised path around the perimeter, similar to a moving walkway) provides continuous views.

This is a genuine conservation exhibit, not simply entertainment. Kelly Tarlton’s participates in the international King Penguin studbook and Gentoo Penguin breeding programmes, with animals transferred between accredited facilities worldwide.

Penguin feeding times: Typically 10:30am and 2:30pm — check the current schedule at booking. Feeding is the most active time in the exhibit and worth timing your visit around.

Penguin backstage experience: An optional upgrade (approximately NZD 60 / USD 36 / EUR 33 on top of entry) allows small groups to enter the Antarctic area (in cold-weather gear provided) and observe the penguins at close range. Minimum age 5; maximum group size 5. This must be pre-booked separately.

Kelly Tarlton’s Sea Life Aquarium Auckland — entry ticket

The shark tunnel

The original concept from 1985 — still operational and impressive. The curved acrylic tunnel (approximately 80 metres long) passes through a large tank containing sand tiger sharks (Carcharias taurus), rays (stingrays, eagle rays), and a variety of reef fish. Visitors stand on a slow-moving travellator while sharks glide overhead and on both sides.

The sand tiger sharks (2-3 metres) are not aggressive toward humans in a contained environment — their alarming appearance (upturned mouth showing multiple teeth, heavy body) is disproportionate to their actual temperament in captivity. They are maintained in the tank at a feeding level that prevents hunger aggression.

The ray tank on the lower level of the shark exhibit allows visitors to observe rays from below through the acrylic floor — a genuinely disorienting perspective.

The stingray touch pool

The shallow touch pool contains common stingrays with the barb removed — allowing safe tactile contact. For children, the sensation of a ray gliding under their hand is one of the most memorable aquatic experiences available without specialist diving.

Note: Removing the barb is standard practice in controlled aquarium settings. The stingrays are not harmed by the process and live normally.

Seahorse Kingdom

A dedicated exhibit for seahorses (the aquarium maintains multiple species including the big-bellied seahorse, New Zealand’s native species — the largest seahorse species in the world). The microscopy tanks show seahorse biology in detail, including the male brood pouch where seahorses gestate their young — a fact that consistently surprises adult visitors.

Practical information

Location: 23 Tamaki Drive, Orakei, Auckland — on the eastern waterfront, approximately 4km from central Auckland. Bus routes 756 and 769 stop at Kelly Tarlton’s. On-site parking is limited; Tamaki Drive has street parking.

Hours: Daily 9:30am–5pm (last entry 4pm). Extended hours during school holidays.

Booking: Online is significantly cheaper than walk-in. Always book online. The Merlin Entertainments annual pass (covers Kelly Tarlton’s, and comparable SEA LIFE attractions worldwide) offers value if visiting multiple attractions.

Duration: Allow 2 to 2.5 hours for a relaxed visit covering all exhibits, including penguin feeding. 90 minutes if moving at a faster pace.

Café: The café at Kelly Tarlton’s is adequate but not destination-worthy. Better to have lunch at Mission Bay (5-minute walk along the waterfront) before or after, where multiple good café and restaurant options face the beach.

Combining Kelly Tarlton’s with other Auckland activities

Tamaki Drive waterfront walk: The walk from Kelly Tarlton’s west toward Mission Bay Beach, Kohimarama, and St Heliers along Tamaki Drive is a beautiful urban coastal walk (approximately 3km each direction). Combine a Kelly Tarlton’s visit with this walk for a full morning/afternoon.

Mission Bay Beach: 5 minutes east of Kelly Tarlton’s — a popular Auckland swimming beach (usually calm, lifeguarded in summer). Good for families to decompress after the aquarium.

Auckland Museum: For families doing both Kelly Tarlton’s and Auckland Museum, the logical sequence is Kelly Tarlton’s in the morning (open from 9:30am) and Auckland Museum in the afternoon (closes 5pm). Total time: a full day.

Honest assessment: is it worth the money?

Kelly Tarlton’s is a mid-tier attraction — more impressive than a basic aquarium, less impressive than a major metropolitan aquarium like the Sydney Aquarium or the Melbourne Aquarium. The penguin colony is genuinely excellent and justifies the visit for families with children. The shark tunnel remains impressive despite its age.

For adults without children: the value proposition is weaker. NZD 39 is not a trivial entry fee for what is approximately 2 hours of content. The Auckland Museum (NZD 32 entry) offers more for adults in terms of intellectual depth.

Verdict: For families with children aged 3-12 — Worth it, especially the penguin colony and shark tunnel. For adults without children — Spend the money on Auckland Museum instead.

Frequently asked questions

Can babies attend Kelly Tarlton’s?

Children under 3 are free. The aquarium is pram-accessible throughout. The cold temperatures in the Antarctic exhibit (approximately 4-8°C in the visitor walkway, though not as cold as the penguin area itself) may require wrapping up infants.

How does Kelly Tarlton’s compare to the Melbourne Aquarium?

Melbourne Aquarium is larger, has a greater species variety, and includes crocodiles (not native to New Zealand). Kelly Tarlton’s Antarctic penguin colony is superior to Melbourne’s in terms of enclosure quality and species authenticity. If visiting both Australia and New Zealand, see both.

Is there a discount for New Zealand residents?

Kelly Tarlton’s does not have a specific resident discount (unlike Auckland Museum). The best discount is online pre-booking (versus walk-in). Merlin annual pass holders receive free entry.

What age range gets the most from Kelly Tarlton’s?

Ages 4-12 are the sweet spot. Children in this range engage fully with the penguin feeding, shark overhead experience, and stingray touch pool. Children under 3 are often either frightened by the shark tunnel or too young to process the experience. Adults find the penguin colony genuinely impressive regardless of age.

Is the aquarium ethical — are the animals well cared for?

Kelly Tarlton’s participates in internationally accredited zoo and aquarium networks (BIAZA, the global SEA LIFE conservation programme). The Antarctic penguins are part of a managed international population programme for species conservation. The enclosures, while not equivalent to natural habitat, are designed to support natural behaviours. This is the standard for accredited facilities; whether you find this ethically sufficient is a personal determination.
