The national model aircraft body, Model Flying NZ have details on their site,
www.nzmaa.org.nz. We do need to follow CAA rules in relation to where we can (or cannot) fly etc.
For large models, here are the rules...
Legally, this Certification Process gives effect to CAA regulations and to NZMAA
safety rules as follows:Category 1: Models 15kg – 25kgAuthority is delegated to NZMAA by CAA to issue Permits to Fly to owners of
radio controlled model aircraft in the weight range 15kg – 25kg. It is illegal
under NZ law for models of this weight to be flown without written permission
from NZMAA. Certification is also required by NZMAA safety rules.
Category 2: Models 25kg – 100kg (in law, actually ‘pilotless aircraft’)CAA authorizes NZMAA to manage the certification process and to
recommend that CAA issues written permits to owners of pilotless aircraft in
the range 25kg – 100kg, to be flown for recreational use only. NZMAA has
sole authority from CAA to inspect such aircraft, to make recommendations to
CAA, and to issue Permits to Fly at Public Sites, relating to aircraft/pilot
combinations. Certification is also required by NZMAA safety rules.
Category 3: Models less than 15kg but with IC motors 75cc or electric motors
5,000 watts input or larger
NZMAA safety rules require that these models be certificated.
For those that are interested in some slightly smaller modelling, here is my gallery from the Hamilton Model AeroClub's amphibian flyin early last year...
