Surfdaddy,
Palliser Bay would be a good choice, I am not overly familiar with the place but that bit of coastline is exposed to swell from south, east and nor east. The prevailing winds are probably nor easters, and southerlies, I am sure that if I have got it wrong, some will correct the posting.
I live in the South Island, checkout surf.co.canterbury, http://www.surf.co.nz/regions/canterbury/surfReport.asp?camera=SumnerBar
The following; Sumner, New Brighton, Taylors Mistake, Akaroa peninsular and Kaikoura combined, are probably the most consistent surf spots in Aotearoa (Land of the long white cloud) NZ. We are now still in winter, check out http://www.niwa.cri.nz/services/cam-era/sites/piercam/latestimage in our day time, it is now 12.43 pm, you will see snow on the foothills. Hence, skiing/snowboarding only 1-2 hours away Check out Mt Hutt NZ.
We are still not totally averse to foreign investment in our coastal real-estate, probably the cheapest non-third world coastal land you could buy, however resistance is gathering to the incredible price-increases resulting from not only foreign investors but also NZers who want to return home, post Sept 11, who have cashed up and will pay anything for that dream bit of land. Prices have probably doubled to tripled in the last 12 months.
Aotearoa is a temperate country, wetsuits all year round these days. My personal preference would be the Sunshine Coast, Noosa, anywhere around there, warmer, mild winter, and every where a break, not overly crowded, even in the school vacation times. Not sure on their Immigration rules, ours are tightening up as well.
