Faatoafe entered not guilty pleas today on all charges and was remanded on bail for a case review next month.
Whetton, the 6ft-4in (1.93m) flanker who was part of the 1987 World Cup winning side with his twin brother Gary, is named as one of the victims in court documents.
It's alleged that on March 9, this year, Faatoafe got hold of Whetton's Visa card details without claim of right with intent to obtain a pecuniary advantage dishonestly.
The same day, police say Faatoafe used the details to book Air New Zealand flights valued at $1,327.
Yesterday, Whetton, 54, said he wasn't left out of pocket, but was left wondering how his credit card details were accessed.
"How they get hold of the thing, I don't know," he said.
"Through Air New Zealand I guess is how they do it. It wasn't through the wallet."
Air New Zealand said today that Faatoafe had never worked for the airline.
"I can confirm that Ainea Harrison Faatoafe has never been employed by Air New Zealand nor has he had access to customers' credit card information through any of our secure payment systems," a spokesman said.
"As this issue is currently before the courts, we are not able to make any further comment at this time."
