The idea isn't that wild as Doctor Who recently started to expand where they shoot. Recently a few episodes were shot in the US instead of the UK (primarly South Wales.) Steve Moffat who is currently at the helm for Doctor Who recently worked with Peter Jackson and Steven Spielberg as one of the writers for Tin-Tin. So all the dots connect. Doing a few episodes in New Zealand would fit really well but knowing Jackson the episode would turn into a three parter. Watch this space.
