we went last weekend, very cool exhibit! life size model of a huge great white shark! awesome. the preserved giant crabs and deep sea fish were also cool to see. we sat on bean bags watching that underwater screen for ages!
i'm also gonna mention, in the museum itself there is also a large area dedicated to fish and the ocean, and a few fish tanks set up throughout. morays, marine, nz marine, nz native, crayfish etc etc
and it's free :thup:
