Whether they are taking visitors for private tours around the district's sights and activities, picking cruise passengers up from the Port of Tauranga, transporting people to and from airports or doing the driving for groups on wine tours of the Hawkes Bay, the focus is firmly on fun.
"We don't go to work, we go to play - that's the Grumpy's way."
And that is paying off for Grumpy's, with the Flashoffs reporting significant repeat business.
"We have clients who use us the whole time they are here. We pick them up from the airport, take them everywhere for three or four days, then drop them back at the airport. It's great, you really get to know them."
The Grumpy's way has been instilled in all staff and Grumpy said each individual then puts their own touch on their tours.
"They don't work for us, they work with us and there is a great atmosphere. That's how we succeed - by enjoying what we do."
Winning the award has only reinforced that success, with the company attracting new attention. But the couple are wary of growing too fast.
"The next year is going to be one of consolidation and ensuring everything we do, we do to the best of our ability and with some profitability."
While Grumpy said entering the awards had been time consuming for a smaller company with limited staff resources, the results had been "fantastic" and very beneficial for the business.
"It is all very positive and that's what we try to be. If we are having fun, so are our clients," said Mrs Flashoff.
