Buy your insurance in Papeete. Term that will cover you while you are taking the boat to Zealand or
Australia. Otherwise, let this particular boat go, and wait till you can arrange insurance with the company of your choice. From memory, there aren't many "hurricane holes" in FP. Furthermore, the southern hemisphere cyclone season, is really from about the middle of October (had to seek a marina in
New Caledonia at that time for cyclone protection when we had guests); and as late as the middle of May (one crossed over us at Raoul Island between NZ and
Tonga an earlier year). So don't make the assumption that it will be a clear run to NZ. Usually they reach NZ as subtropical storms, still tricky sailing, and risky. You'll have to pay a LOT and might need specialist insurance for such a trip. The
weather gods don't seem to care about human aspirations at all. If you are particularly seasoned sailors, it could be doable and an adventure; at worst, it would be life threatening. If a cyclone goes over you directly, you will experience a 180 deg.
wind shift, and it really stirs up the seas something fierce.
