Trackside presenters are fixtures at feature New Zealand race meetings and their presence is believed to boost the profile and turnover of the events.
Several racegoers at Sunday's meeting expressed their disappointment to the Otago Daily Times that Trackside had not sent a presenter to Oamaru's feature annual thoroughbred meeting.
Club president John Foley was also disappointed with the situation, he said.
''It would have been good on the day to show everyone what we had done. I think we made something special during what can be a pretty ordinary time of year - winter racing.''
The New Zealand Racing Board, which runs Trackside, apologised in a statement to the Oamaru Jockey Club for not sending a presenter to the meeting.
''We accept that in this case an error was made in our on-course presentation allocation and we have contacted the Oamaru Jockey Club to apologise.''
NZRB said turnover drove the decision on whether a presenter was sent to a race meeting.
''In general, the Trackside team allocate on-course presenters on the basis of a meeting's historical betting turnover and industry standing. We also take into account other factors such as the day's schedule of racing.''
NZRB did not address inquiries asking whether the coverage of Otago and Southland thoroughbred meetings was a priority for Trackside.
Trackside had an on-course presenter at the Rangiora harness racing meeting the same day.
The Rangiora meeting featured seven mostly low-grade harness races with stakes totalling $59,000.
TAB totalisator win pools for the Rangiora meeting totalled $83,941.00 with an average of $11,991.57 per race.
The Oamaru cup meeting featured key open-class lead-up races to the Grand National carnival with stakes totalling $207,500.
Oamaru's totalisator win pools totalled $273,045 with an average of $30,338.33 per race.
The New Zealand Racing Desk did not provide coverage of the Oamaru meeting over the weekend.
It provides media outlets and social media accounts across Australasia with news about New Zealand thoroughbred events.
The news service is run by New Zealand Thoroughbred Marketing and funded by New Zealand Thoroughbred Racing.
NZTM chief executive officer Andrew Birch acknowledged the lack of coverage of the Oamaru meeting.
''It was disappointing the Oamaru Cup wasn't covered in written form on Sunday.''
''The matter has been addressed and I am pleased there has been follow-up coverage this week.''
