Police say the crashes highlight the need for safety from motorcyclists and motorists.
Mr Blair's widow, Karyn, said drivers needed to heed warnings and be more observant, considerate and patient. "We need to look. We need to all take a little bit longer at intersections. There is nothing that you are going to that is so important that you need to take a human life on the way."
Mr Blair was killed at Wardville, just 5km from his Te Aroha home and at a blackspot he knew had claimed lives before. Mrs Blair said breaking the news to their children Sophia, 18, Libby, 15, Jeremy, 14, and Jack, 11, was harder than having to identify her husband's body at the scene.
"No mum should ever have to tell their babies that their daddy's dead. It's going to have a massive impact on our family."
They will leave the farm at the end of the dairy season, and Mrs Blair said she would have to travel through the fatal intersection regularly, which would be "extremely hard".
She wanted people to know her partner of 24 years was not just another road statistic.
"He's not just a name in a death notice. He was a real person."
Mr Blair, who had ridden motorbikes all his life, was so safety-conscious that it was "utter disbelief" he died on one, Mrs Blair said.
She hoped by telling her husband's story it would help save lives, or at least make drivers more aware of motorcyclists.
Waikato road policing manager Inspector Freda Grace said every road death was a tragedy.
"These are people's lives and if they are seriously injured they have the potential to be life-changing ... It's a tragedy for them, their family and their friends. It's just really sad."
Mrs Grace said there was very little room for error on motorcycles compared with driving a car.
