An immigration adviser said some people were treating the arrangement as a "loophole" for easy entry into New Zealand.
The Herald has been told of one person, a Chinese passport holder, who was allowed in after showing that he had a $20 e-ticket for the Bangladesh-Scotland game in Nelson.
But the man told an immigration adviser he had no intention of going to the game, and had used the ticket only to support his case for entry.
The adviser, who wanted to remain anonymous, said the man had a restaurant job waiting and had inquired about ways to stay in New Zealand permanently.
Another adviser, Tony Tse, said the price in China to fraudulently obtain a New Zealand visa was 100,000 ($21,800) to 120,000 renminbi. The price of a World Cup ticket was therefore "a bargain" for would-be rule-breakers, he said.
Mr Tse said there were fears some bogus cup "visitors" could be coming with plans to work and overstay.
As of Wednesday, 94 people had travelled to New Zealand under the arrangement but some had been stopped from boarding their flights.
Immigration New Zealand spokeswoman Rachel Purdom said several Chinese nationals were denied boarding in Australia on Monday.
"The passengers [said] that they would be attending the games and provided Cricket World Cup tickets as evidence. However, the tickets were for games scheduled to take place after the dates of [their] planned departure, which called into question [their] intentions."
The New Zealand Association for Migration and Investment said people coming under the scheme should be "risk assessed".
Immigration Minister Michael Woodhouse was not available for comment yesterday.
The Cricket World Cup runs from February 14 to March 29, but the visa arrangement gives extra time for fans to visit before and after the event.
