It was clear the motorbike failed to take the corner properly but it was not clear why, she said.
It was not known whether any other vehicle was involved or when the crash happened.
The weekend started in tragic fashion late on Friday afternoon, when 78-year-old Paul Potama, of Tangimoana, was killed in a single-car crash near the town.
A few hours later, in the early hours of Saturday morning, a motorcyclist died on Baverstock Rd in Hamilton.
Police said they believed the 30-year-old man had fled officers earlier in the night.
Waikato District road policing manager Inspector Freda Grace said any road death was a tragedy and police extended their sympathy to the man's family.
His name has not yet been released and no further details were available this morning, a police spokesman said.
The weekend was also marred by a number of serious crashes in which people were badly injured.
In South Auckland, the drivers of a car and truck were seriously injured when their vehicles collided on State Highway 25 about 6.25am.
The truck and trailer rolled on to its side, leaving hundreds of bottles of beer broken and strewn across the highway.
The injured drivers were flown to Waikato Hospital by helicopter.
A Waikato Hospital spokeswoman said the female driver from the Saturday morning crash in South Auckland was in a serious condition in the high dependency unit.
The male driver from the Saturday morning crash had been discharged, she said.
Firefighters worked to cut an injured driver from her car after a high-speed collision on Sunday sent another vehicle careening up to 60m into a roadside paddock near Carterton in Wairarapa.
Carterton Deputy Fire Chief Brian Styles said the two cars collided at the intersection of East Taratahi Rd and SH2 just before noon.
An unrelated collision involving another two vehicles occurred on SH2 near Neiches Lane about 4.25pm the same day.
Mr Styles said two fire crews from Carterton and a crew from Masterton had been scrambled to each of the crashes, which left several travellers with injuries ranging from minor to serious.
Earlier in the day, SH2 through Waikino Gorge was shut for a few hours in the morning after a 16-year-old woman crashed the car she was driving.
She was trapped for a while and was taken to Waikato Hospital by helicopter with serious injuries.
