Getting that "blame coronavirus" message out early is smart. Labour already suffers from the persistent perception that they're not as good at running the economy as the other lot are. Of course, no one can blame Labour for coronavirus' arrival, but opponents might yet accuse them of mishandling the attempts to keep it out. And, anything that sounds like "they made this worse" could only reinforce that "can't run the economy" narrative.
That criticism is emerging already. The university sector's been particularly vocal, claiming that it stands to lose $170 million if the travel restrictions keep their international students out. The universities have proven very, very good at making noise in the past, so they're a formidable opponent. They want the travel restrictions waived for incoming students and they're making sure everyone knows that.
The hospitality sector wants tax cuts, the tourism sector needs help. So far, the pleas for help have been cordial, but the longer this goes on, the greater the risk of criticism.
Business confidence is falling again. The latest ANZ survey shows a drop, even though only a third of the survey was taken after the travel restrictions were imposed. Again, in the lead up to an election, it's uncomfortable to have the words "business confidence falling" floating about to remind us of all that shade the business community threw at the government for months.
There is a potential upside here for the government, which is that it could use this downturn to justify increased spending during the budget and election. Robertson is already hinting that New Zealanders need to have the blow cushioned by the government. There are range of tools from benefit increases to tax cuts to straight out Hong Kong-style hand outs.
If that works well, this could become Robertson's hero moment. The Christchurch Earthquake was a hero moment for Bill English and John Key. They ended up earning the credit for steering the country through a difficult emotional and economic time, and voters forgave the years of ongoing deficits.
Worst-case scenario, it doesn't work, the old narrative kicks in, and Labour gets punished for coronavirus at the election.
