Mr Rose said the Department of Labour was investigating and had already visited the farm.
Mr Goodin, who had been taken to Wairarapa Hospital, was to undergo surgery on his leg.
Wairarapa hospital spokeswoman Jan McLaren said he had broken his leg and was in a stable condition.
Mr Rose said Mr Goodin had several years of experience driving the Polaris UTV and the farm had a perfect safety record before the incident, which reinforced the need to remain alert and cautious whenever operating farm vehicles.
He said the UTV is equipped with safety features, including seatbelts and a roll cage, although Mr Goodin was not wearing the belt when the machine toppled over.
"It's supposed to be the safest vehicle there is and, if Bill had been on a quad bike, things would probably have gone worse for him," Mr Rose said.
"I arrived at the scene about five minutes after all the drama and it was still quite a shock. It really highlights the fact that you can never be too confident and it's better to play it safe. There is no room for complacency.
"You really have to treat these machines with respect."
There were three quad bike accidents in three months on Wairarapa farms up to the end of December 2012, including the death of Kahutara School pupil Shane William White, 10, who was killed in a quad bike crash on a South Wairarapa farm on October 10.
A crash on November 20 involving a quad bike at a Pirinoa farm left a 24-year-old woman with ankle injuries, after her machine flipped while she was travelling at speed over flat terrain. And long-time farmer Ian Perry received broken ribs when he rolled a quad bike on his Tinui farm on December 27.
A 65-year-old Tinui farmer received serious head injuries after crashing a quad bike on his Rewa Rewa Rd property early last year.
