Kiwis living overseas and part of the Team of Six Million group are vowing to keep up the fight against charging for managed isolation.
The minister in charge of the border, Megan Woods, yesterday announced that the charges would apply from Tuesday.
Lamia Imam, who lives in Texas, and Alexis Harris, who lives in London, are part of the group that runs the "Team of Six Million" Facebook page.
Imam told Morning Report the charges may be coming into force but the group is still dead set against them.
"We continue to highlight the stories of people who are impacted by this and we still want to keep the conversation going because we want to be able to show how unfair this quarantine fee is."
Harris said the group had not ruled out legal action.
"We're keeping our options open. We've been engaging with lawyers throughout the process."
