Visa requirements for Australian citizens and permanent residents traveling to New Zealand
Australian citizens and permanent residents do not usually require a visa for travel to New Zealand, unless they are a person with significant character issues as described in Sections 15 and 16 of the Immigration Act 2009.
Provided they enter New Zealand on a valid passport, Australian citizens and permanent residents will normally be granted a resident visa at the airport to stay in New Zealand.
