Can whv in New Zealand go to Australia and return to New Zealand?

Mainly depends on how long lz will stay in Australia. There is also the long-term planning of lz.

If you only hold whv from New Zealand, you have to go to the Australian Embassy to apply for an Australian visa. It usually takes three days to sign a transit visa. )

But if the purpose of lz is to stay in New Zealand, but whv is about to expire. Lz can choose to renew other types of visas locally. Like learning sign language.

I hope my answer can reach you!
