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).
