The NZ and NSW school holidays both start this weekend as the Games finish.
Both are major tourist markets for the Gold Coast, delivering a combined 1.2 million visitors a year.
The Queensland, NSW and NZ school holidays all coincided last year but Winter said this year's scheduling has "not been kind to us".
He said the traditionally bumper Easter holidays had been "slow" with tourists coming for the Games opting for short stays.
While admitting some traders may have missed out on Games business, Winter dismissed claims that parts of the Coast had resembled a "ghost town".
"Ghost town is so far off the mark that it really doesn't warrant any honest response," he said.
"This Commonwealth Games has met all the expectations we had and we set the bar very, very high. Notwithstanding that, it's fair to say there have been some traders who haven't had their expectations met."
Winter said hotel occupancy had picked up in recent days from around 71 per cent to 81 per cent and tourism officials were "very pleased".
Hotels which had been banking on a Games boom were forced to slash room rates to fill rooms.
"There was never going to be 100 per cent occupancy," Winter said, adding that the Coast's average annual occupancy rate was 71.6 per cent.
