The drop this time indicates people are losing their patience with the measures they are being asked to take - and blaming the Government for it. The mood is turning.
It is a message to Ardern to rattle her dags to deliver on a way out of it, and mop up long-standing messes such as MIQ.
That message is reinforced by the results for Act. The only winners in the poll were the Act Party's David Seymour, and NZ First which had notched up to three per cent.
Both Seymour and Winston Peters have been the bluntest of the critics of the Government's handling of the various elements of Covid-19.
As for Judith Collins, she need not take heart from National's result of 26 per cent compared to the paltry 21 per cent National got in a Taxpayers' Union Curia poll taken at the start of the month.
Because National too had dropped in the 1News Colmar Brunton poll. Yet again it was Act that profited.
Collins' 5 per cent result as preferred prime minister is one of the worst ever seen for an Opposition leader.
Nor has National made up any ground since its election result.
Collins was initially brought in as the night watchman to see National through to the election after Muller stepped down.
She did that, but is now still at the crease dead-batting when the party needs a batter who can at least hit steady singles – if not a few boundaries.
The voters are not making the job of the selectors easy. All the speculation about Simon Bridges taking over again has not resulted in a lift for him in the polls – he is at two per cent.
In recent days, Sir John Key subbed himself in as leader of the Opposition and delivered a batting masterclass. launching his stinging critique of many aspects of the Government's handling of the Covid-19 response.
In the absence of that big hitter in the current National caucus, the batter the voters have turned to appears to be David Seymour.
