Last week police raided two Auckland properties and seized 933 tickets with a combined value of more than $500,000. Cash was also recovered.
Police allege the tickets were bought using false credit card details.
Detective Superintendent Andy Lovelock said police believed some tickets had been sold to unsuspecting buyers but he said he could not release the ticket numbers.
He said police had not ruled out further charges.
"There are matters still under investigation."
He warned people buying Rugby World Cup tickets to approach official sellers.
"Wisdom tells you it is always best to buy from bonafide ticket sellers because a bargain may not turn out to be a bargain."
Police have worked closely with tournament officials since the fraud was detected and the fraudulently-purchased tickets were made void as a result.
A third man, Fusani Seed, had also been charged in relation to the scam.
He had been facing a charge of obtaining by deception $1528 worth of Rugby World Tickets.
The 42-year-old is understood to have returned to South Africa.
