Homeowners affected by the Bella Vista debacle are going to take a class action suit against Tauranga City Council.
The announcement comes after two families have already said they were going to sue the council.
Now, the other 19 families will join them.
The homeowners met outside the affected properties in The Lakes near Tauriko this morning.
They were joined by members of the public and media outlets as they made the announcement.
Tauranga City Council mayor Greg Brownless and other elected council members were also invited to the meeting, but homeowners say they declined the invititation.
During the meeting, homeowners said they "are exhausted and hoped it wouldn't come to this".
"It's a decision that hasn't been made lightly."
Nathan Smith has been appointed as the lawyer as homeowners proceed with the legal action.
The news comes amid council's plans to prosecute the developer involved in the Bella Vista debacle.
