Stewards established the last rain in the Matamata area of the track had been nine days earlier and that the only irrigation following that rain had been in the vicinity of 15mm.
Further investigations were to follow.
The meeting will not be re-scheduled as the majority of horses who didn't race at Matamata have options at Hawke's Bay, Tauranga and Ellerslie over the next nine days.
New Zealand Thoroughbred Racing, in association with the respective clubs, will look to divide races where possible at these meetings.
Grylls has five rides at Ellerslie today and will continue to ride here until the resumption of Singapore racing on January 1.
"I am lucky that they've granted me a further six months to my licence," he said as he got dressed yesterday immediately following the abandonment.
The former Waikato horseman says he will stay put in Singapore while he continues to be licensed by the Singapore Turf Club.
"It's a privilege to be able to ride there.
Two race days a week, no travelling, good stake money — it's a great package."
Grylls has been a freelance jockey, but did some riding for ex-pat Kiwi Laurie Laxon before his return to New Zealand more recently for Australian Lee Freedman, who bought Laxon's business.
He was aboard Lee Freedman's first Singapore runner, Mr Clint, and won on him.
He is a Power 3-year-old from the Zabeel mare Victoria Belle, from a Danehill mare from a Centaine mare.
Grylls has an opinion of the colt which Laxon retains an ownership share in after paying $95,000 for him at New Zealand Bloodstock's 2016 Ready To Run sale.
"Being from a Zabeel mare he will be better as he steps up in distance," says Grylls.
As an after thought, Grylls came up with another good reason to be in Singapore.
"I live 10 minutes from the track and ride a bike there."
What, for fitness?
"No, it's an electrified scooter."
