Hi Tate6 and All :cool
We've been living in Tauranga for about seven months now and really enjoy it. Having lived in San Diego it reminds me a lot of that area, only without the high prices and the crowds. Mount Maunganui reminds me of La Jolla...but still not as pricey or she-she.
Property prices are higher than most places, but they continue to appreciate while most areas of NZ are now flat so it's still a good investment. It's easy to get most anywhere, locally and around the country, has a nice airport and the weather is wonderful.
As Ruthy points out, there are plenty of things to do, nightlife, etc. and the people are very nice to boot.
Traffic is a bit of an issue during rush hour (seems like they are working on every road at the same time!

) but rush hour is just that, about an hour and then things settle down.
Schools are reported to be very good here, the air is clean and crime is low. It used to be known as "seizure world" for all of the retirees, but that is rapidly changing as the population continues to grow.
You can live in Tauranga proper or there are a lot of small communities both north and south.
We haven't visited every town but checked out a number of places on the North Island and decided to settle here. We can recommend it!
