Lobby group Hobson's Pledge has hit back at the New Zealand Council of Trade Unions (CTU) with an attack ad of its own - this one taking aim at Labour leader Chris Hipkins.
Hobson's Pledge, led by former National Party leader Don Brash, has published an ad featuring a black and white Hipkins with the caption: "Delivers division, not outcomes."
"New Zealanders are fed up with divisive politics," said a Facebook post by Hobson's Pledge, accompanied by an image of the ad in Saturday's NZ Herald.
It comes just weeks after the CTU rolled out a series of attack ads describing National leader Christopher Luxon as "out of touch" and "too much risk".
Attack ads have become a feature of this year's election campaign. On Tuesday, Labour launched a new ad featuring a cartoon of Luxon and ACT leader David Seymour - questioning what cuts the two parties would make in Government such as public transport fares and public services.
But a day later, National fired back with a re-working of Labour's ad using similar imagery.
"Labour has been wasting taxpayer money for way too long," the ad said.
