[QUOTE=rossad;1272210]West north west off Cape Reinga top of NZ is an area that gets hit everyweek this time of year. The Tasman shouldnt be crossed unless the weather
is totally worked out. 60 knots can be regular with heavy breaking waves. Going north quickly away from the top and getting past the SPCZ as soon as possible.
You don't cross the South Pacific
convergence zone (SPCZ) going to Aus. It is normally much further north stretching from Solomons to Fiji
and nowhere near their track.
You can never really work out the weather more than about 3 to 5 days in advance, even with the best weather forecaster. On a 10 to 15 day trip across the Tasman, you should be ready for anything.
