New Zealand operates a Multiple Earthed Neutral (MEN) system. The voltage is 400 volts 3 phase, or 230/240 volts single phase at 50 hertz.
The standard domestic connectors and sockets are NZ Standard type 198, 10 amp, flat 3 pin, common only to New Zealand and Australia. For higher amps the New Zealand film industry has standardised to British Standards 4343 or the equivalent European Standard CEE17.
Temporary connections to permanent mains supplies must be carried out by a New Zealand registered electrician.
