Re: New Zealand cruise in April 2013 - skipper/ crew wanted
There is at least one rental company Sunsail?. Those places tend to be expensive and I believe in Auckland require knowledge and experience, possibly = a coastal YM.
The usual response most people get is a reference to harbour racing which is widely available from Westhaven most evenings and weekends.
You can find the details at crew.org.nz.
You are not likely to get much response to a request for a couple of days sailing, as most prefer to have met prospective guests beforehand, although quite possibly you could get a day sail or two.
