Cheers guys.
I plan to see both the Christchurch museum and the Wanaka display (and perhaps the 'Warbirds over Wanaka' airshow in April !).
AFAIK, The RNZN has c. 11 ships.
Didn't see their musum in Auckland though.
It's interesting, a local tour guide in Auckland made derisory comments about the NZ Defence Forces e.g. "we have no air force", "we have old worn out ships" etc.
So it would seem the NZ DF's suffer from negative PR just like the Irish Defence Forces - even though you would expect the NZ DF's to have a high profile - after all they were involved in WW1, WW2, Korea, Vitenam, etc ?!!
