The annual consumer spending amount of $592.2m in Whanganui represented an increase of 7.7 per cent from 2020.
Whanganui & Partners chairman Pahia Turia said the figures compared favourably with national statistics for the same period as well as those for other regions.
"Rather than purely being a case of provincial New Zealand faring better than major centres, Whanganui's metrics also outstrip the likes of Palmerston North and New Plymouth in these areas," he said.
"We do know that some data has a lag effect and, particularly since the introduction of the protection [traffic light] framework, some sectors of the local economy have struggled."
Tourism GDP was down 25.1 per cent on the previous year and logistics, which covers transport and warehousing businesses, was down 7 per cent. Education and training dropped 3.5 per cent and creative industries experienced a GDP decrease of 3.2 per cent.
The two areas that had seen growth were agribusiness with an increase of 5.1 per cent, and manufacturing, which was up 2.8 per cent.
Turia said the downturn for hospitality and other close-contact businesses, which usually relied on tourist numbers in summer, reflected the broader national trend and the impacts of Covid-19 restrictions.
He said Whanganui & Partners was putting additional efforts into a promotional push for autumn and winter that aimed to coincide with Covid-19 management becoming less restrictive for all businesses.
Whanganui's population increased 1 per cent in 2021 to 48,400 in December.
