I don't know where you are flying and therefore which plane you will be on. If you look at your ticket it might say which plane you will be flying. With this information, you can check on seatguru the details of the plane that Air New Zealand will operate.

Looking at the different planes Air New Zealand uses (777 or 767 a priori on your route), there seems to be a minimum of 3 bassinets and up to 6, so I suppose you will likely have one - unless New Zealanders make way more babies than I have seen on flights in general.

Checking in early would probably help as you would get priority over other passengers for these seats.

To Westland maybe?
