Wellington police issued 111 speeding fines yesterday to motorists, including one going 160km/h.
Inspector Wade Jennings said fewer cars on the road in Covid-19 alert level 4 did not mean people could speed.
"People should be isolating at home under Covid-19 level 4 restrictions but if you need to drive, for essential purposes, slow down and drive to the conditions."
Several drivers were caught speeding between 130km/h and145km/h.
Jennings said there was absolutely no excuse for it.
