I had a three day layover on the way to Australia, given how much there is to see in New Zealand I feel like this is a bit cheating to consider visiting g the country. The big decision is next time I want to do some trekking is it in Nepal, China, or New Zealand.
I spent all my time in Auckland. The city is not too walkable but buses run frequently between all areas of the city. The Australia trip started with a bang as I BASE jumped by wire from the city's tallest building.
