"That is a huge change and we saw that with the Auckland lockdown - spending was down. But we did also see that the likes of Wellington, the public service in particular, did start to work from home. And that sucked all the life out of some urban centres."
Auckland, Wellington, Otago and Canterbury were the four worst-performing regions, according to Infometrics, which looked at a range of recent data including retail spending, employment, vehicle registrations and traffic data.
The other interesting trend was how the effect on tourism was starting to show through, Olsen said. The best performing regions were Tasman, Northland, Hawke's Bay, Gisborne and Nelson.
Three things were driving those regions, said Olsen. First, he said, a number of areas that weren't as exposed to international tourism have been able to rebound stronger.
Then there was the primary sector, with good export demand, and pricing, which is holding economic activity at solid levels.
"The challenge there is that we're not expecting the export sector to hold up throughout," Olsen added. "It is going to soften but not as badly as other sectors."
Thirdly, these areas were also a very attractive proposition in terms of where people were moving post-Covid.
"We are seeing people opting to think about where they want to live. And those areas have some really good lifestyle options," Olsen said.
"That speaks to a wider point that we did see across the economy, that people really did get on to that 'buy local' bandwagon. [People] came out and said 'we've saved some money during lockdown' let's get that back into the local community."
That had really showed in Northland spending numbers, for example, he said.
One point of caution was that the numbers recently had started to soften.
"That is as we expected and it does highlight that summer is going to be a very tough period, with tourism hit probably three times as bad as we've seen in recent months."
