I looked up your area, but are you right smack on the coast with salty air and sea wind all day, or are you a few miles inland from that? If you are dealing with a lot of salty air, be sure to choose the figs that say, "Does well at the coast". I have one fig that was rather shocked at first by the wind, and probably by some salt, but it rebounded pretty well.
I'm not finding the temperature ranges that you have. Do you only have frost, or does it get much below freezing? Trying to protect a fig from freezing is a huge job because they get to be so big. here when an occasional winter threatens to get too cold, we use smudge pots, large air blowers to keep the air moving, which raises the temperatures. If you have an orchard it will be a big job to cover them, but I guess it depends on how dedicated you are.
Some Common figs can do well where it freezes. Chicago Hardy fig grows in Canada where it snows. Not all can tolerate those conditions, some need a lot of heat. I am near the coast and I have many cloudy/foggy days in summer, which limits the types I can grow. I have a White Genoa, Peter's Honey Fig, Violette de Bordeaux, which is a really pretty fig.
There's also one kind of fig, a Smyrna fig, that requires a special wasp that probably isn't in New Zealand, and another kind of tree that that wasp lives in to pollinate it. You'll read great descriptions of a Smyrna fig, but unless you've got that rare combination, which is only naturally in the Middle East, and has been imported to California, don't get tempted to try it!
Your local nurseries probably carry the most successful kinds for your area.
