Another poll is showing a clear drop in support for the coalition Government - and some are wondering if it's cause for concern.

The newest  Taxpayers Union-Curia Poll has Labour on 34.1 percent, and National on 33.6 percent - and Hipkins in the lead for preferred Prime Minister.

ACT has fallen 2.3 points to 7.7, and New Zealand First is just above the threshold on 5.1 percent.

Jordan Williams from the Taxpayers' Union says the Government should be concerned about losing favour with voters.

"We are now only 18 months away from Christopher Luxon having to go to the public to ask that fundamental question - do you feel better off than three years ago? Right now, that answer is no."
