Three-phase electric motors
Minimum energy performance standards (MEPS) for three-phase electric motors were introduced in 2002. There was a revision in 2006 and a subsequent revision has been proposed.
MEPS for motors are prescribed in the joint Australia/New Zealand Standard AS/NZS 1359.5. The Standard covers motors rated from 0.73 kW up to but not including 185 kW, in 2-, 4-, 6- and 8-pole configurations, and includes voltages rated up to 1100 V a.c.
In addition to specifying minimum efficiency values for motors, the Standard also specifies the minimum efficiency that a motor needs to meet in order to be able to claim "high efficiency".
Importers and manufacturers may not sell three phase electric motors unless they are tested and comply with the Energy Efficiency (Energy Using Products) Regulations 2002.
Regulatory requirements
There are steps you must take to meet the requirements of Energy Efficiency (Energy Using Products) Regulations 2002.

Standards
The current version of the electric motors Standard is available from Standards New Zealand.
MEPS for motors increased from 2006
To lift motor efficiency to a new level, the MEPS and high efficiency requirements for motors were increased on 16 June 2006. These new requirements replaced the 2002 requirements.
Read the consultation paper for electric motors - 2006 revision.
Further increases in the MEPS levels for motors may be considered if warranted, however at this stage no work has been undertaken in this area.
