Stiffer penalties are to be imposed on fare dodgers on commuter trains in Auckland from Sunday.
Auckland Transport believes up to 10% of passengers are travelling without a ticket, at a cost of up to $2 million each year.
The penalty fare is now $20, almost double.
But transport board chairman Lester Levy said the increased penalty will not be enough to eliminate the problem and the agency is putting other measures in place.
One of the options will be to install electronic ticket gates at four more stations, meaning 80% of passengers would have to pass through the barriers.
