Police are urging the public to slow down around roadworks, following numerous reports of high-risk driving on the Albany Highway.
Auckland Transport are carrying out roadworks, which are scheduled to be completed in 2017.
Several parts of the road have a temporary 30k per hour speed limit, which are clearly signposted.
Police say drivers appear to be ignoring the lowered speed limit and are travelling at high speeds through the roadworks.
"Recently, we issued 39 speed infringement notices in just two hours in that area.
We caught someone who was driving at 79 k's per hour through the 30k zone" says Snr Sgt Brett Campbell-Howard, Waitemata Police.
