Permaculture in New Zealand

So im 25 years old, working fulltime to pay the bills 1/6 of y wages perweek is used to buy food.

I own my own home which i intend to finish up and sell to purchase a peice of land in the central waikato area!

I was introduced to the idea of Permaculture through a freind and of cource gained my basic gardening knowledge through my Mother.

Building a Straw bale home it the goal with thi peice of land and also a forest garden based on permaculture principles to supply my family with fesh produce year round.

As the house building idea is years away, the obvious step would be to get Planning and Planting ASAP thefore they have time to grow and can start produceing before i even build a house.

A shelter belt is first on the list, to protect from the cold southerly winds, (1), Any idea's for planting a shelter belt? Productive trees? bushes? obviously needs to act as a shelter and idd like it to be functional aswell,
