COVID-19 might have been challenging for populist governments, but that hasnt stopped populist strains emerging in the run-up to New Zealands general election in October.

Populism, as commonly defined, embraces an ideology that divides society between the pure people and the corrupt elite. It contends the will of the people requires leadership promoting mono-culturalism, traditionalism and opposition to globalist plans within the deep state.

We have already seen some of these themes playing out in the current contest to govern New Zealand.

Having hired prominent Leave.EU campaigners Arron Banks and Andy Wigmore (the self-styled bad boys of Brexit), New Zealand Firsts social media strategy has begun to reflect their brash strategic advice.

Party leader and Deputy Prime Minister Winston Peters has claimed New Zealand Firsts common sense is a safeguard against the woke pixie dust of the Labour and Green parties. He has cast himself as the the defender of socially conservative values like the right to believe in God.

Meanwhile, the National Party appeared to adopt a more partisan strategy after the renewed outbreak of COVID-19 in Auckland.

Leader Judith Collins said the return of the virus would come as a shock to all New Zealanders who believed what we had been told. She complained Health Minister Chris Hipkins had been reluctant to brief her own health spokesperson, Shane Reti.

Her deputy, Gerry Brownlee, took it further, implying Jacinda Arderns government had known more about the resurgence of the virus than it was publicly acknowledging. He said New Zealanders had been left in a position of wondering what do the health authorities know that they are not fully explaining.

Where National was taking advice is unclear, but it has in the past had direct and indirect links with conservative research and polling organisation Crosby Textor and Topham Guerin, the social media agency that helped Boris Johnson win the 2019 UK election.

To be fair to Peters, he joined other political leaders in criticising Nationals position as undermining democracy.

However, he also joined Nationals questioning of his own coalition governments decision to grant refugee status to Kurdish-Iranian journalist Behrouz Boochani, asking why he had jumped the queue. Peters was accused of race-baiting in return.

Populist lines of attack may be born out of electoral weakness and political expediency, but they are risky at a time when Arderns handling of the worst global pandemic since 1918 has boosted her national and international standing.

Moreover, the performance of populist governments in dealing with COVID-19 has been woeful, which hardly boosts the credibility of populist posturing over the pandemic in New Zealand.

Take Boris Johnsons original argument in favour of a herd immunity strategy to avoid disrupting the economy: You could take it on the chin [] and allow the disease, as it were, to move through the population.

By mid-March the World Health Organisation (WHO) was publicly questioning the absence of any clinical evidence to support this response, and the Johnson government was ordering a strict national lockdown to suppress the virus.

Now, senior cabinet ministers, including the prime minister, are facing possible prosecution for alleged misconduct in public office, which some say has led to over 60,000 avoidable deaths.

In the US, President Donald Trump responded to warnings about a potential pandemic from the WHO, intelligence agencies and senior officials between late 2019 and March 2020 by reassuring Americans they had nothing to worry about.

Only on March 17 did Trump publicly concede there was a highly contagious invisible enemy. But by prioritising the opening of Americas businesses and schools over a lockdown strategy, Trump undermined efforts to overcome dire shortages of PPE and ventilators in a pandemic that has now taken more than 170,000 American lives.

The inability of the Johnson and Trump governments to deal effectively with a real-world problem like COVID-19 is no coincidence.

Both seemed indifferent to WHO warnings on January 30 that the coronavirus was a public health emergency of international concern. They appeared impervious to the concerns of many health-care experts, emphasised a sense of national exceptionalism, and were painfully slow to react as the threat grew.

In contrast, the response by Arderns government placed New Zealand in the company of states like South Korea, Taiwan, Singapore, Germany and Vietnam that have managed to keep virus-related deaths to relatively low levels.

What they have in common is a willingness to heed WHO advice, consult with scientific and health experts, and learn from each other.

To be sure, the Ardern government must be held accountable for its handling of the pandemic. But opposition for oppositions sake is not the answer in a major health crisis.

Politicians taking advice from those peddling misinformation and populist conspiracy theories run the risk of undermining public health messages and weakening the capacity of the country to suppress a deadly threat.

Furthermore, such tactics have already proved useless against a virus that plays only by the rules of science and objective reality.

To date, there are few signs that many New Zealand voters will be tempted by a politics-first, science-second approach during the COVID-19 crisis. Politicians who take this approach run the risk of a backlash.
