Contact tracing arrangements between our two countries are also a really important way of keeping New Zealand safe during this time. Travellers to Australia from New Zealand must use the local state contact tracing app when they are there. The country's apps are not interoperable. Similarly, visitors to New Zealand will be asked to download the New Zealand contract tracer app and instructed on how to use it. Contact details from travellers are available through a number of sources, and that can be accessed by our finding service should we need to trace back following an outbreak in Australia.
