Police hope 33 new speed cameras will help make our roads safer.
The devices have been installed at sites around the country identified as having a high crash risk.
They're being rolled out as part of the third phase of the $10 million static camera expansion programme announced in July 2013.
Independent experts used data on fatal and injury crashes that have occurred nearby to decide where the cameras should go.
A full list of the locations wasn't avaiable tonight, but police have announced five cameras have gone up in Otago, two are in the Auckland City police district and one has been installed in Counties Manukau. All will start operating next week.
Inspector Peter McKennie, operations manager of road policing, said international research showed speed cameras encouraged drivers to slow down and reduced speeds helped reduced injuries and fatalities on roads.
"Road crashes have devastating impacts on families and communities."
McKennie denied speed cameras were used to collect revenue, saying money from camera infringements went to the Crown's consolidated fund, not to police
"We're only interested in the impact the cameras have on encouraging people to slow down to safe and appropriate speeds, so they get to their destination safely."
McKennie also reiterated other road safety messages.
"All road users have a part to play in keeping our roads safe," he said.
"We encourage drivers to protect themselves and their families by driving to the conditions and within the speed limit, driving sober and alert, and making sure everyone in the car wears a safety belt. Let's work together and make sure everybody gets where they're going safely."
