Crowds in summer holidays and weekends. Available from Windscene Mission Bay. Heaps of parking and grass rigging, windsurf shop and school , and McDonalds nearby. Tamaki Beach Yacht Club . Just west of Mission Bay, Tamaki has been the focal point of windsurfing in Auckland from early on, although the only real thing in it's favour is it's the best spot in the prevailing SW, and is sailable on all tides.
Slalom sailing is best in a westerly, with a good chop in strong conditions.
Access to the Tamaki River is either from Glendowie Yacht Club or Bucklands Beach. Best in SW which is strong. Other S - W directions are good. Flat, short chop. Waist deep in mid tides.
