US boater visiting

I am trying to make it to NZ after a working trip to Austalia. Looking for Class IV-V+ stuff. Have no gear with me as I am on a business trip. If anyone could email me any info on a plan of attack (rentals, travel, camping, etc), it would be greatly appreciated. Probably would make it to NZ on 2/17. Where to fly into would be first question. Travel plan next. Thanks for any help.
