Tried finding a windsurfing, wingfoiling, etc. forum in New Zealand but couldn't find anything. Saw a cool video of wingfoilers having a great time in Takapuna, looks like nice conditions for winging.
Might visit in the future and want to know where to be for the best intermediate wingfoiling. Anyone know of any local forums?

I would start with the wingfoiling forum here on Seabreeze.com.au, they may know.

Try getting in touch with Heidi at Water Nomads on FB or try NZ Boardstore.

There's a fairly active FB group called 'Kiwi Foil Froth' which seems to be mainly about winging. Join them and maybe ask there about forums?

Yes good call for Boardstore.
Also FB Auckland Windsurf Sessions. Takapuna is classic NE spot and easy launch of boat ramp.
In Auckland when you have NW to SW there are a number of different locations depending on where you are and tides.
Taranaki is DTL Wavesailing and is rocky, gusty on the inside but AWESOME ??

Awesome, thanks a lot guys! Can't wait to get there some day, maybe this December. If anyone comes to Vancouver Island or Vancouver-to-Squamish, Wind Is Good .com/ BigWave Dave .ca (can't post links) is our local forum, forecast, buy/sell, etc. website.
