This is a major transit centre for moving international tourists in and out of NZ, so you would think it would be a happening, thriving centre. Plus it has the highest populas in NZ. Go up the Skytower and to the museum, then go to your next destination. Or if you have more than 2 days in Auckland go to the islands just north if the city-v beautiful.
Insider Tip:You don't really need more than a few days here. Take the airport express bus to get you to and from the airport (the big blue one) as it only charges $16 each way, not the pricey airport shuttle which charged $35.
