Are there any regulations that limit starting currents or which mandate the installation of “Soft Start Devices” for air conditioning units in Australia and New Zealand?

Yes. Some electrical network operators in Australia do set limits on the maximum start current that an air conditioner can demand – to meet these limits, soft starters are usually required (i.e. to limit in-rush current to acceptable limits). An overview of the respective State, Territory and New Zealand requirements are set out in the summary of service and installation requirements – this page has links to information on soft start / maximum current requirements. Australian regulations for energy efficiency do not directly prescribe soft start technology for air-conditioning equipment.
