The stewards had offered jockeys from previous races time to air their concerns.
Some riders didn't feel entirely comfortable with the surface.
Jockey Opie Bosson, he said, also had reported that his mount had "shifted" near the 800m mark.
The club had made a submission to use the groundhog or ground breaker to rough up the slippery surface but several jockeys had proposed they would have ridden conservatively regardless.
"We took a cautious approach to their riding [which] raised questions about the competitiveness of the race meeting."
Postponing the meeting wasn't the stewards' call once a track was deemed unsafe, Neal said.
"That's a matter for the club and the racing board to sort out."
The groundhog hadn't been used in New Zealand for the past three years and its use previously in Dunedin showed "no anecdotal evidence to suggest they are 100 per cent successful", he argued.
While trainers, owners and jockeys were unhappy to lose a premier race day, the stewards had to follow the letter of the law.
