Waka Kotahi (NZTA) aims to have 200 speed cameras by next year, 50 more than the current number in place across the country, the transport agency says.
The current tools in place include 90 police cameras, 42 Auckland Transport cameras and three Christchurch City Council red light cameras.
"Over time, the plan is to increase the number of safety cameras throughout the country," said Tara Macmillan, NZTA's head of regulatory strategic programmes.
"We are still deciding on the number of cameras and mixture of camera types to use, to deliver the most effective outcomes."
It comes as a process is underway to transfer existing speed cameras from police to NZTA, which was expected to happen by the middle of next year.
New Zealand was one of the most dangerous OECD countries when it came to roading deaths, data showed.
Macmillan said the tools planned to be rolled out next year would consist of 50 "additional safety camera sites".
"Road safety traffic cameras are a key road safety intervention and contribute to reducing deaths and serious injuries by encouraging people to drive at safe speeds."
Macmillan said NZTA was putting systems in place for when the cameras are transferred to the agency.
"We will also process offences for safety cameras operated by other road controlling authorities," she said.
"NZTA's current focus is on the establishment of systems, processes and capability to enable the safety camera system operation, preparing for the migration of NZ Police cameras and rolling out a small number of new camera sites in a managed way."
The total number of cameras to be installed beyond 2025 has yet to be finalised, she said.
In October, average speed safety cameras started rolling out across Auckland. Those tools can calculate the average speed a vehicle travels down a road between two cameras.
Additionally, a six-month trial of safety cameras last year looked at how many people used their phones while driving as well as passengers who weren't wearing seatbelts.
Results from the May-November 2022 trial across three sites found 2.4 percent were detected illegally using mobile phones, while 1 percent of vehicles had occupants not wearing seatbelts.
