Opposition leader Chris Hipkins has overtaken the Prime Minister on net favourability, as support dropped for the coalition.

A Taxpayers' Union-Curia poll had Chris Luxon tumbling 13 points to negative five percent, with Hipkins up 4 points to three percent.

Both ACT and New Zealand First leaders have also seen a drop, with David Seymour down 11 points and Winston Peters down 14 points.

ZB senior political correspondent Barry Soper says it'll be a while before voters see what the Government has achieved.
