The track was inspected yesterday by stipendiary steward Matthew Williamson and Trainers' Association representative Nigel Tiley.
"You can't emphasise enough that there are no issues with safety on the track.
"It is simply about how long it would have taken for the track to recover," said Tiley.
"Derek Nolan and my wife, Lee, rode two horses on the course proper this morning and they both said the track was perfectly safe."
Mitchell said the decision to abandon was to avoid the same result either just before racing started today or during the meeting.
"I've had trainers call me and say 'thanks for being pro-active'. A couple said they'd taken multiple horses to last week's Hawera meeting and had the races called off before a race had been run."
Mitchell said he was attending Monday's course managers meeting in Wellington and will investigate to where the Counties June 22 meeting may be transferred to help the track bed in.
"That will give the track the decent break it needs," he said.
