I would like to relocate to a lovely town where it is not too hot or humid. Where is good?

It depends on which areas you have narrowed down. Anywhere on the mid north coast (coastal towns ie old bar) are fine but as soon as you head 10km in land you can be up against 40+ humid summers

Hi not sure if your still wanting to move, but there are a couple nice towns called hyland park, valla and urunga these areas are very nice and have most facilities needed in a town
