We will be arriving in Aukland from Canada. I would like to avoid getting New Zealand dollars before arriving as it is expensive to do so here. My bank (Scotiabank) is part of the Global Banking Alliance which means we can withdraw cash from Westpac ATMs without fees. there seems to be a Westpac ATM at the airport in the domestic area. We would like to get cash there and then take the Super Shuttle into Aukland. Is this doable?
