Certain dog-tracking devices are illegal in New Zealand because they operate on the same radio frequencies as equipment used by people travelling and working in rural areas, such as forestry workers, Department of Conservation rangers, or search and rescue crew. This spectrum is licensed to those operators and must not be used by other devices.

Legislation: The Radiocommunications Regulations (Prohibited Equipment – Dog Tracking Devices) Notice 2014 prohibits the importation of radio equipment (and their parts) used for, or with the primary purpose of being used for, tracking or locating dogs or other animals that operate in the frequencies 151.820 MHz, 151.880 MHz, 151.940 MHz, 154.570 MHz and 154.600 MHz, including, but not limited to, the following makes and models operating within these frequencies:

Garmin Alpha 100
Garmin Astro 220 system
Garmin Astro 320 system
Garmin DC 20 collar
Garmin DC 30 collar
Garmin DC 40 collar
SportDOG TEK equipment.
Before you buy, be sure to check whether the device may be imported, is acceptable for use in New Zealand, and authorised for a radio licence.
