Kas,
"Ships Cat" is based in Wellington, yet he is away sailing now ,around the north tip of the southern island.. I am sure when he comes home and sees your post he will contact you...also the local sailing clubs will find someone to take you out.. contact them, Kiwis are the second friendliest people in the world ( after the Aussies) pity they cannot play sport <>>>> ( bloody good sailors though, but dont tell them I said that!!!!!!!!! )
enjoy NZ..
