Auckland's Waterview tunnel has made the Government a whopping $2.5 million in fines in eight months.
With four cameras operating in the tunnel, figures released to NZME under the Official Information Act show 29,047 speed-camera notices were issued to drivers between July 4 2017 and March 7 2018.
There was, however, a drop in the infringement rate since the first six weeks of the tunnels' opening where motorists were issued $948,220 in tickets.
New Zealand Police national road policing manager Superintendent Steve Greally said the number of tickets issued shows people are continuing to speed.
"[They] are therefore putting themselves and others at risk. This is always of concern," Mr Greally said.
"Consequently, any driver travelling over the set speed limit can expect to be ticketed."
People have expressed concern over the tunnel's cameras with one woman calling it a "money-making tube", the Herald said.
