The business awards are delivered annually by the Rotorua Business Chamber of Commerce with a total of 10 awards handed out this year.
A humble Rigter said the award came out of the blue and it was still sinking in.
Neither he and Red Staff Timber entered the awards this year because of the extra demands on the company due to Covid-19 which made the win sweeter.
Rigter has clocked up more than three decades in the industry, including 22 years at Red Stag Timber, a company owned by Marty Verry and Louise Dinmore.
Red Stag Timber is known as the world's most advanced sawmill and the first super-mill in the Southern Hemisphere.
In 2003 it nearly went bust but Rigter said things turned around when the Verry family took over. He said since then the company's performance and fortunes had gone from strength to strength.
Asked the secret to his success as one of Rotorua's top business leader, Rigter said it was a combination of factors but at the heart of all was the people he worked with.
"It's using all the industry knowledge I've gained over the years, having a clear vision and direction where to take the business, and having built a strong team around me."
Rigter said this award may have his name on it but it was also in recognition of the company's successes thanks to all the business' motivated staff.
"It's all about our people, including my senior management team and from our production staff right down to our cleaners, who all play their part in our achievements.
"You can't do what you do without the support of amazing staff."
Rotorua Chamber of Commerce chief executive Bryce Heard said Rigter rightly deserved this award.
In terms of the award criteria, Rigter "ticked all the boxes," he said.
"Tim is the sort of leader who flies under the radar. He just gets on with what he does best under the radar and without seeking the limelight.
"He is a very quiet, capable excellent leader and because of his great people skills, he's very popular with staff. And also well-liked and respected in the Rotorua community.
Rigter was also a great supporter of various community organisations and charities, he said.
