Lived in NZ for four years and Oz for 25.
Living in NZ is a bit like stepping back in time to Oz say the late '70s... Auckland
is a lovely city but the rest of NZ seems to hate Aucklanders. If you pull into a small town and visit the local RSA club the first thing the locals will ask you is "you're not from bloody Auckland
are you" if you say you are they will snarl at you and ignore you. If you are from outside of Auckland they will be your new best mates. I felt they generally liked Ozis more than Aucklanders.
The economy and wages are a lot smaller in NZ, jobs are harder to find. Housing is a lot cheaper.
As others have said I believe Auckland has great sailing and sailors. Morton bay is big and shallow but you can be up around Fraser Island and the GBR in a couple of days. Glasshouse Mountains look cool.
area has had serious rain and flooding in the last few years. Weather
is great generally in Brissy.
Hobart (possibly comparable or better than Auckland) has really good accessible cruising, but the weather
is cool also.
Another vote for Brisbane
being "Australias' most boring city".
