Drivers have been mistakenly fined for speeding on a stretch of road in Christchurch due to the speed limit signs being incorrect for seven years.
From Garlands Rd to the Tunnel Rd intersection on Port Hills Rd there were 50km/h speed limit signs - but the area was actually meant to have a speed limit of 60km/h.
However, the signs were never changed to reflect the 60km/h speed limit.
NZTA has changed the signs after police discovered the error while preparing for a court case, Stuff reports.
The speed limit of 60km/h was announced in a notice in the New Zealand Gazette in March 2011 and was due to be enforced in mid-April.
But the Christchurch earthquake meant the installation of the signs was put off as other projects took priority, NZTA told Stuff.
Police are beginning a process to refund any fines issued over the past seven years as a result of the incorrect signs, and those affected will be contacted by mail.
