Foss said the guide would help councils, the New Zealand Transport Agency and other road controlling authorities decide where and when to make safety improvements or change speed limits.
"New Zealand roads are unique and conditions vary from towns to cities, north to south. The guide strongly encourages community involvement as local knowledge and perspectives, backed by the information and data provided in the guide, will help ensure the best possible safety results."
The speed management guide will replace the speed setting guidance in the Land Transport Rule: Setting of Speed Limits 2003. Consultation on the changes will begin early next year.
A 110km/h limit has been considered for some time for motorways built as part of the Government's roads of national significance programme.
Other roads are expected to be Transmission Gully motorway and Kapiti Expressway in the Wellington region, and the Northern Gateway toll road north of Auckland.
