In my opinion there's only one choice - Cape Karikari. Stay at either the Whatuwhiwhi Top 10 Holiday Park (Harris and Janette are totally kayak fishing friendly) or the DOC camp at Matai Bay itself. Top 10 have fantastic facilities including excellent showers and a proper fish cleaning station and freezers. The DOC camp is nicely maintained but has the typical basic facilities. The fishing is fantastic and there are multiple launch options ranging from almost out of the front of your tent to less than 15 minutes drive if wind directions change. I consider this a kayak anglers "must do".

  wagener holiday park at houhora heads ,water at your dr step by camp ground, heads only a two minute paddle  might as well say same area as karikari pen,I will be up that way for two weeks from chch on tues 30th for a fishing trip but I stay at family further on,pm me if you want to know more about the area  

What about the top of Coro, camping at Fantail, PJ, Stoney bay and Waikauwau, lotsa options if the wind changes and lotsa fishy territory.
