One hundred and seven cancelled tickets to Saturday night's All Blacks- Wales Test in Hamilton may have been on-sold to unsuspecting rugby fans.
Anyone who didn't buy tickets through official outlets is urged to check theirs to ensure they're not from a batch cancelled after they were accidentally delivered to a wrong address.
The Waikato Rugby Union has been unable to recover them and has lodged a complaint with the police, who are now investigating.
The cancelled seats are in the front row area of the Uncovered Wel Networks Stand and in the Brian Perry stand.
The numbers are posted on www.mooloo.co.nz.
