"We need to keep working on strengthening all aspects - vehicles, speed, roads and roadsides and road use," said Mr Woodhouse.
He said a previous action plan in 2011-12 contained 108 individual actions - with approximately 90 per cent of them being completed or underway.
"Taking a system-wide approach and sharing responsibility with stakeholders, partners and the public gives us the greatest chance of making our roads safer for everyone and builds on the great work achieved from the first action plan," he said.
New Zealand Transport Agency chief executive Geoff Dangerfield said the agency had been closely involved in the development of the plan
He said NZTA would work closely with police, the Ministry of Transport, ACC and other road safety partners to implement the plan and reduce deaths and injuries on the roads.
"Death and serious injury should not be an inevitable part of road use. With this action plan, we can keep up momentum up in improving road safety across our whole road system, refusing to accept that any road death is inevitable.''
