"We are disappointed to lose the meeting and for the locals but we didn't have any other option because of the travel restrictions," said NZTR chief executive Bernard Saundry.
NZTR will likely programme a replacement meeting in the horse-rich Waikato region next week, almost certainly on Wednesday, but if Level 3 is still in place in the Auckland region by then horses from north of the Bombay will almost certainly be excluded.
That leaves two thoroughbred meetings this week - Waverley on Friday and Riccarton on Saturday - while the Cambridge harness racing meeting which was to have been held tomorrow night has moved to Saturday starting at noon.
Harness Racing New Zealand have had to set up an unusual set of contingencies for that meeting as they do not know if horses trained north of Bombay will be allowed to compete.
At this stage the whole meeting has simply moved, meaning the same fields that were going to race on Thursday night will race Saturday.
But if, as many people expect, the Auckland region's restrictions remain over the weekend then horses from there will be scratched and HRNZ will have in the background compiled an idea for a new meeting using only horses from south of Bombays.
"That isn't ideal but it means if the Auckland region horses can't start we can have a smaller meeting with the local and Central Districts horses," says HRNZ's Darrin Williams.
"We can't just scratch the Auckland horses because then we would end up with 11 races but some very small numbers in some of them. That call will be made Friday."
All race meetings around the country will be run as workplaces with only essential racing industry personnel permitted but both codes are confident racing and training will continue at both Level 2 and Level 3, which would mean Alexandra Park could still race next week because there are enough horses in the region to hold a meeting.
*** Superstars Catalyst and Avantage gave racing fans at least something to smile about when they dazzled in the two star-studded trials held before the Taupo meeting today.
Catalyst showed improved barrier manners to win his 1100m catchweight heat and heads to Sydney next month while Avantage was very strong in the closing stages of her heat to beat Supera and races at Te Rapa on September 5 before heading to at least the first two Group 1 races at Hastings.
