Collins acknowledged a one-way travel system could work - as seen with travellers coming into New Zealand from the Cook Islands.
"The Government has indicated that a travel bubble is possible in the current settings by allowing quarantine-free travel from the Cook Islands, since January.
"Managed isolation is overrun with long delays because places are being taken up by Kiwis returning from Australia when there is little - if any - risk of Covid-19," she said.
Those sought-after spots in managed isolation and quarantine could be given to people who are returning from other parts of the world or workers and families of those needed to return to work here.
She said the public had been told for months that a transtasman bubble was on the cards. However, the borders remained closed.
"The Government must make this a priority. New Zealanders deserve action now."
