She also used the live video to reiterate the ongoing discussions around the possibility of a "trans-Tasman bubble" which would allow international travel between Australia and New Zealand before other countries. No timeline for the plan has so far been announced by either government.
"New Zealand has had a thriving tourism industry before, and we will again," she said. "Think about exploring your backyard."
