New Zealand Prime Minister Jacinda Ardern is set to decide by Monday whether a general election will go ahead on Sept. 19, with most analysts expecting her to resist opposition calls for a delay due to a flare up in coronavirus infections.A country of five million people, a long way from anywhere, New Zealand has fared far better than most countries during the pandemic, but a spate of new infections forced Ardern earlier this week to lockdown Auckland, the largest city.Seven new cases were reported on Saturday.
