Property Brokers Whanganui's team leader of residential sales, Shona Howe, said the team was stoked.
"Whenever you win a premier award, it is a real reinforcement that you're running a good business," she said.
Garner said the judges found the company excelled in the areas of team culture, service, and its connection and support for the community.
Howe said Property Brokers wanted to support the communities they were based in.
The sales staff at the business supported local schools and organisations such as the SPCA, as well as local young athletes.
Howe said there was a big focus within the business on health and wellbeing - asking people to keep their work/life balance.
"At the end of the day, a smart business doesn't want to have stressed and overworked people working there," Howe said.
This year had been slower for them due to the property market coming down off the high of skyrocketing over the last two years, but the company had still been very active.
Howe was expecting the company to continue to build on the reputation they had gained, and expected the housing market to stabilise in 2023.
"We're putting our best foot forward - we're always trying to come up with new innovations and more things we can do to support the community."
