Hello
We have been here 6 months now and I would guess we know the town reasonably well. Depends what sort of info you are looking for. Some useful websites are below, if you would like to know more specifics just ask and I will help where I can.
For the record, Whangarei has a pop of approx. 48,000. It is small, but vibrant. Do not believe the myth that it rains all the time, because it doesn't, the weather is warm, Northland is known as the winterless north.

Should keep you going for a while!!
Whangarei is about 2 hour drive north of Auckland, has good recreation facilities etc........I guess it just depends what you are looking for.
Let me know if I can help more.
