hmmm... more info.
Ok.
Water temp in the summer months is low 20's in the winter it can get down to 10 deg C. Its not a tropical location. but if you can get over colder water for insane wind and waves then you will have a blast.
Taranaki is the place to go for waves.
Fiztroy beach in New Plymouth is a very nice spot with consistant waves and cross on wind running sept through to march.
Kina road/Tai road (just north of opunake) has insane surf. Its a gnarly spot with cliffs and boulders jutting out of the surf. Today is good example. 40-55 knots and a wave set height of 5.5 meters!!!!
only the craziest of bastards would fly today!!
www.swellmap.com/surfing/new-zealand/kina-road. Raglan is the home of the Ozone design team. Why do they choose raglan? there some 300+ days a year you can kite there. Epic flat water spot and on the outgoing tide they can kite in 5-6 knots. Its called the magic carpet.
Foxton has an awesome flat water estury and the beach is 100km long. you could do a down winder until your exhuasted.
Auckland has beaches on every angle and its 40 mins from one side of the island to the other. If there is wind you can find a spot to kite irrespective of direction.
sept through to april the prevailing wind is westerly and all the west coast beaches and locations are fair came.
Waikanai, muriwai, baileys, 90mile all epic. The east coast is scattered with tones of good kitable spots aswell. I have less knowledge of them however.
