What is "Consumer Rocketry"?- Consumer rocketry is a term used to describe rocketry activities pursued by hobbyists, teachers
and other people who are not involved in the commercial applications of
rocketry. These activities involve enthusiasts in constructing,flying
and recovering lightweight models of real rockets. These models are
normally described as either 'model', 'advanced', high power', or
amatuer and experimental rockets.
'Flying model rockets' come in various shapes,
sizes and configurations. There are simple
model rockets, scale model rockets, multi stage
rockets, rockets which are powered by more
than one motor (clusters), rocket boosted gliders,
rocket boosted radio controlled gliders and
rotorocs- rockets recovered by helicopter type rotors.

What
is the difference between a "model rocket", "advanced model rocket",
"high power
rocket" or "experimental rocket"?
The two regulations governing rocketry in
New Zealand (The HSNO Regulations and the
Civil Aviation Rule Part 101), are normally
concerned with the total rocket vehicle, that is ,
the rocket airframe and motor combined.
Generally speaking however, when rocketeers refer to a 'model rocket' or low power motor
they are referring to rockets with no metal structural parts powered by commercially
manufactured motors in the power ranges "A"
to"D". A 'large' or 'advanced model rocket'
motor means a rocket with no metal
structural parts,powered by a commercially
manufactered motor in the ranges "E" to "H".
[ Note that Civil Aviation Rules define a 'large' model rocket as:
- using between 25 and 125 grammes of propellant (about E to H power)
- producing between 20 and 320 Newton Seconds of total impulse (about E to H power)
- using a slow burning propellant
- made of lightweight materials
- having no airframe parts made from metal;
- having a gross lift off mass not exceeding 1.5 kg]
A 'high power rocket' refers to a
rocket with no metal structural parts powered by a
commercially manufactured motor in the power ranges H to N. An
amateur or rocket
experimental rocket is anything that falls outside of the above catagories.
All the above types of rocket are flown from a launch pad, use electrically ignited
rocket motors (which are purchased
separately from the rocket kit itself), and are designed
to be recovered by various means, eg
parachute, to enable them to be flown time and time
again.
To fly a model rocket you require a launch pad, a launch
controller to ignite the motors,
flameproof recovery wadding and a selection
of model rocket motors (which include
igniters).

Where can I buy model rockets in New Zealand?
Model rocket kits and model rocket
motors are freely available in New Zealand from several
hobby shops,with coverage in
Dargaville, Whangarei, Auckland, Papakura, Hamilton,
Cambridge, Palmerston North, Lower Hutt and Nelson. List of
Retailers. If not available in
your area, they can be purchased from AEROSPACE EDUCATION, Box 13 386 Onehunga
Auckland, who market Quest, Aerotech, MRC, Estes and Public Missiles brands.
Advanced model rocket motors (E to G)
and High Power rocket motors (H to N) and
catalogues are
also available from AEROSPACE EDUCATION.

How old do I have to be to purchase a model rocket motor?
Model Rocketry motors are recommended for ages 10 to adult with adult supervision
recommended for ages 12 years and under. Advanced Rocketry motors are recommended
for ages 16 to adult with adult
supervision recommended under this age group. High
Power rocketry
motors are recommended for age groups 18 and over again with adult
supervision recommended under this age limit.
In New Zealand, however, at the
present time, you must be at least 18 years old to
purchase
any type of rocket motor. In 1992 the New Zealand government agreed to
reduce the purchasing age limit for motors in the ranges A to D to 14 years of age,
however this legislation has yet to emerge.

What regulations currently govern the use of model and high power rocketry in
New Zealand?
Users of model rockets and large (advanced) model rockets must legally abide by
the Model Rocket Safety Code (published with each rocket kit or motor pack).
If flying above D power, a permit is
required. This can be obtained from the Dept of Labour
or arranged for you by Aerospace Education within 24 to 48 hours. Membership of the
New Zealand Rocketry Association may be of some benefit to you in obtaining a permit.
There are no Civil Aviation
Restrictions on flying 'model rockets' however users of 'large',
'high power' and experimental need to abide by Civil Aviation Rule Part 101.
Briefly, these rules state:
Large, High Power and Experimental Rockets
You cannot operate these rockets above 400 ft AGL (AGL means "above ground level")
within 8km of an aerodrome boundary, without the permission of the airport operator or
Air Traffic Control.
You cannot, without prior permission,
launch into controlled airspace without authorisation
from the Air Traffic Control unit responsible for that area.
'Controlled Airspace ' differs from
location to location. To determine whether your launch will
breach controlled airspace you need
to either refer to an aeronautical map or contact the
ATC supervisor in your area
(phone 0800 626 756, ask to speak to the supervisor).
You cannot fly or drop an object from a
rocket in a manner hazardous to aircraft, persons or
property.
You cannot fly when there is more
than 4/8ths cloud coverage, or the horizontal visibility is
less than 8km, or fly any rocket into any cloud.
