Unfortunately due to family commitments i am unable to make it on trips such as these. But one area you may not know about is just north of waipapa point. At the southern end of the passing lane in the trees theres a turn off left then you head north along beside the rail line then take a track to the beach theres a heap of room for pitching tents and its sheltered too with the beach only hundred metres away. Weather suiting this is anything of westerly orientation. Its a great spot very deep water and not far from the rocks with an excellent camping area im picking it could well be the spot your looking for possibly.
