The dino material from New Zealand is so scanty and fragmentary that it would be impossible to gauge if their owners were adapted to cold climates or not. There's no evidence pro or con from that direction.

The only 'special adaptations' in the anatomy that might be correlated with prolonged cold or dark are: (1) insulative body covering and (2) larger eyes (e.g. _Leallynasaura_ - though I'm open to the opinion that its big orbits are a juvenile feature).
