Lamb - oh so tender. Not like the mutton they try to pass off as lamb in California.
The venison is good, too. It's farmed rather than wild, which may account for its non-gaminess.
Green mussels. We discovered these in Havelock, near Nelson. Quite yummy.
Kiwis have a dessert called pavlova, which is a merengue with fruit on top. I haven't yet tried it, but suppose I should if I get to immigrate. I'm just not a fan of merengue.
