You’re standing in a tunnel. Above you, a three-metre sand tiger shark glides by, its jagged teeth just inches from the glass. To your left, a massive stingray—looking like a sentient, flapping pancake—ripples through the water. This isn’t a scene from a high-budget thriller; it’s just a Tuesday at Sea Life Kelly Tarlton’s.
Most people know it as "that aquarium in the old sewage tanks." It sounds gross, right? Honestly, it’s one of the coolest pieces of engineering history in New Zealand. Back in 1985, Kelly Tarlton, a legendary diver and treasure hunter, looked at disused stormwater and sewage tanks and saw a world-class marine sanctuary. He didn’t just build an aquarium; he pioneered the curved acrylic tunnels that almost every major aquarium in the world uses today.
Basically, if you’ve ever walked through a glass shark tunnel in Dubai or London, you can thank a guy from Auckland who liked to tinker with old aircraft parts.
The Man Behind the Glass
Kelly Tarlton wasn't your typical businessman. He was a pioneer. A bit of a "do-it-yourself" genius who once built a buoyancy compensator suit out of garden hose and waterproof canvas. He spent years salvage-diving for shipwrecks, finding gold and French anchors, before deciding he wanted to bring the ocean to the people.
Sadly, he died only seven weeks after the aquarium opened. He was only 47. He never got to see how his "Underwater World" would become a global blueprint for marine education. Today, the place is officially called Sea Life Kelly Tarlton’s, and it’s evolved way beyond just looking at fish through glass.
Penguins, Ice, and the "Stinky" Truth
Let’s talk about the penguins. Specifically, the Antarctic Ice Adventure. It is home to New Zealand's only colony of Sub-Antarctic King and Gentoo penguins.
When you walk in, the temperature drops. Fast. You’re watching these birds waddle around on real ice, diving into freezing water with a grace that definitely contradicts their clumsy land-walk.
- The King Penguins: The tall, regal ones with the orange "headphones" on their necks.
- The Gentoos: The smaller, faster ones with the white "bonnet" markings.
A lot of people ask: "Does it smell?" Well, yeah. It’s a colony of birds that eat fish. It’s going to have a certain... aroma. But you get used to it within three minutes because you’re too busy watching a Gentoo zoom past the glass at 35km/h.
If you’re feeling extra, you can actually book a Penguin Passport. You suit up in Antarctic gear and go out onto the ice. You’re literally inches away from them while they get fed. It’s not cheap—usually starting around $160 NZD—but it’s one of those "bucket list" things that actually lives up to the hype.
What People Get Wrong About the Sharks
The Shark Tunnel is the heart of the experience. It’s a 110-metre long walkway on a slow-moving conveyor belt. You can just stand there and let the ocean move around you.
One big misconception? That these sharks are "scary."
In reality, the sand tiger sharks (also known as grey nurse sharks) are surprisingly chill. They look terrifying because they can’t close their mouths properly, so their teeth are always on display. But they’re actually quite sluggish. They share the tank with Wobbegongs—sharks that look like shag carpets—and massive Broadnose Sevengill sharks.
Pro Tip for 2026:
If you want to actually get in with them, the Shark Cage Snorkel is still the go-to. You don't need scuba certification. You’re in a cage, but the mesh is wide enough that you feel completely immersed. It costs about $110 to $130 NZD depending on when you book. Honestly, seeing a shark's eye move as it watches you is a core memory kind of moment.
It’s Actually a Hospital
People often overlook the conservation side. Sea Life Kelly Tarlton’s runs New Zealand's only turtle hospital.
Green Sea Turtles and Loggerheads often wash up on North Island beaches "cold-stunned" or injured by boat strikes and plastic. The team here spends months (sometimes years) nursing them back to health.
Each turtle costs about $10,000 to rehabilitate. When you pay for a ticket, a chunk of that goes toward things like $60-a-day squid diets for a sick turtle named "Kiwi." You can see the rehab tanks in the Turtle Bay area. It’s a sobering reminder that the ocean isn't just a playground; it's a fragile system that needs us to stop throwing plastic in it.
Planning Your Visit (The Real Talk)
Don’t just show up at 11:00 AM on a Saturday. You’ll be surrounded by 400 screaming toddlers. It’s a nightmare.
Best Time to Visit:
Weekdays after 1:30 PM are the sweet spot. The school groups have usually left, and the morning rush has died down. The aquarium stays open until 5:00 PM (last entry at 4:00 PM), so you’ve got plenty of time to loop the shark tunnel three times if you want.
Current 2026 Pricing (Estimates based on recent shifts):
- Adults: ~$45 - $50 NZD (Cheaper if you book online)
- Children (2-15): ~$32 - $36 NZD

Beyond the Fish
There are some quirky spots that most people breeze past but are totally worth a look:
- Scott’s Hut: It’s a replica of the hut used by Captain Robert Falcon Scott on his ill-fated 1910 Antarctic expedition. It smells like old wood and history.
- Seahorse Kingdom: They have Spiny Sea Dragons here. They look like floating seaweed. If you blink, you’ll miss them.
- The Shipwreck Discovery: It’s full of "treasure" Kelly Tarlton actually found on the seafloor. It’s the perfect bridge between his life as a diver and the aquarium he built.
Is It Worth It?
Look, there are bigger aquariums in the world. There are flashier ones. But Kelly Tarlton’s has a soul. It feels like a passion project that got really, really big. Whether you’re a local who haven't been since a primary school trip in 1998, or a tourist looking for something to do on a rainy Auckland day, it holds up.

It’s a mix of Kiwi "Number 8 wire" ingenuity and genuine marine science. And honestly, standing under a swimming shark never gets old.
