Thanks for the answers,
I've had no issues with using NAIPS for PNG and the Solomons or for the major NZ airports but it seems that NZKK isn't accessable from the Australian system.
Groggie - Aeroweather I have on the iphone but NZKK isn't listed there either.
S2K - I've got a u/n and p/w with IFIS but will try and get one for metservice.
Sounds like someone needs to come up with an iphone app like NAIPS for NZ with a "one stop shop" for all MET and NOTAM info.
Thanks all for the help.
FJ.
