If you were really were retiring and not doing B&B as a main concern I would suggest Howick in Eastern suburbs of Auckland as the weather is good, lots of restaurants, clubs and outdoor pursuits with 5 different beaches within a few minutes walk or drive away, and there is easy access to the ferry for trips into Auckland central or out to the islands, like Waiheke. My husband and I are retired and have been living there on holiday on and off for 10 years and have finally made the decision that life permanently there is the best one for us as it has so much going for it. We have had immigration approval so we are now in the throes of researching shipping agents. Yippee!
