A Rotorua principal believes his pupils have been ripped off about $6000 after 300 counterfeit tickets were used at its gala.
Westbrook School principal Colin Watkins said the "wind was knocked completely out of us" when the fake tickets were discovered after the school's gala last week.
"We get our tickets made commercially so they are all exactly the same size and dimension. While we were counting them after the gala a few of the teachers started noticing tickets that were slightly smaller, a slightly lighter shade of blue and with a photocopier mark."
Mr Watkins said the tickets changed colour every year and went on sale a week before the gala to avoid long queues on the day. Each ticket was worth $1 and were used to avoid cash being stored at the event.
"The amount we have lost from these tickets is much greater than their $1 value as they have been used on stalls to win prizes and buy items. We know at least 60 of the tickets were used on the spinning wheel for raffles and the dollar value of those raffle prizes were between $100 and $300.
