About a third of the Bay of Plenty police officers nabbed for speeding in police cars last year had no valid excuse.
Figures released to the Bay of Plenty Times under the Official Information Act reveal 38 speed camera tickets were issued to police vehicles in 2011. Of these, 24 were waived and 14 fines were paid.
All of the fines were issued by permanent speed cameras or mobile speed camera vans.
Acting national road policing manager Acting Superintendent Rob Morgan said there were strict criteria for waiving fines.
"A notice is usually only waived when a legal defence applies for police officers undertaking urgent duty driving and responding to an incident."
