Where did the NZ styles go?
The Brewers Association styles specifically include international categories where hop character is outside the specific definitions of certain styles.
They also note that given, say, an American Pale Ale, hope character should be reminiscent of American hop varieties, though this may be achieved by skillful use of hops of other national origins.
As always, it is up to you, the brewer, to decide where your beer fits and enter it accordingly. It's not what you used that counts, it's how the beer presents to the judges on the day.
