A faction of six Wellington City councillors have lost confidence in the capital's $7.4 billion transport plan.

The councillors have filed a notice of motion stating they're no longer confident in Let's Get Wellington Moving and want the council to withdraw from their 2019 funding agreement.

One of the Wellington councillors who signed was Diane Calvert, who says an earlier briefing gave them no more confidence in the plan.

"We keep waiting and waiting for Let's Get Wellington Moving to provide us with all the answers that we have at the time. We had a briefing from them last Friday afternoon and it gave us no more confidence."
