What are we consulting on?

We’re seeking general feedback on speed limits on all roads within Porirua City, plus five (5) key proposals:

  1. Schools: We are proposing a range of permanent speed limit reductions to 30km/h on roads adjoining schools where traffic (vehicle, cycle, pedestrian) is generated continuously by other adjacent land uses (for example shops, transport hubs, car parks) through the day in addition to school traffic
  2. Schools: We are proposing a range of variable speed limit changes to 30km/h on roads adjoining schools where significant increases in traffic (vehicle, cycle, pedestrian) is generated immediately before and after school by the school. During other periods volumes of all traffic are low
  3. Road corridors with 70 km/h speed limits: We have been asked to review all 70 km/h road corridors in the city and recommend an alternative safe and appropriate speed. We are recommending a change to 50km/h in on the 70km/h sections of Titahi Bay Road and Papakōwhai Road.
  4. Town/village centres and marae: We are proposing to reduce the speed limit to 30km/h through some of our city and village centres, and around some marae. These are:
  • Takapūwāhia Marae
  • Hongoeka Marae.
  • Horouta Marae.
  • Maraeroa Marae.
  • Porirua city centre.
  • Kenepuru Landing.
  • Plimmerton township
  • Pāuatahanui township.

5. Waitangirua Link Road: Council is proposing to increase the speed limit on the Waitangirua Link Road, up from 50 km/h to a maximum of 70 km/h (i.e. either 60 km//h or 70km/h). The proposal is for 70km/h based on a speed survey, which showed the average operating speed for this road is approximately 64 km/h.


Speed is an important factor in transport. Speeds directly affect the mobility of persons and goods travelling from one location to another. Driving speeds also have a direct impact on the risk of the driver and other people being involved and severely injured in a crash as well as on noise and pollutant emissions. Setting speed limits on different road types is often not just as simple as following strict safety criteria developed for each road type.

We must consider several challenges when deciding on speed limits, such as balancing safety and mobility aspects. In New Zealand, the social cost of a road crash or a road injury includes the following components: reduction in quality of life; loss of output due to temporary incapacitation; medical costs; legal costs; and vehicle damage costs. The behaviour of road users is an important determinant of a country’s road safety performance. Inappropriate speed, in particular, is one of the main causes of road crashes.

Porirua City is responsible for developing, maintaining, and operating the network of local roads, including setting speed limits and delivering public transport infrastructure and services. Decisions on construction, maintenance and management of the road networks must also consider road safety. Road to Zero is the result of extensive engagement with the sector and a nationwide consultation process.

Road to Zero adopts a vision of a New Zealand where no one is killed or seriously injured in road crashes, which is based on a “Vision Zero” approach to road safety. Road to Zero sets a target for reducing annual deaths and serious injuries by 40% by 2030 to track towards the strategy’s long-term aspirational vision. The government policy statement on land transport 2021 introduces a new Road to Zero activity class.

This document sets out how money from the National Land Transport Fund is allocated towards achieving the government’s transport priorities. Investment through the Road to Zero activity class will be targeted towards those interventions identified as being key to achieving the targeted reductions in deaths and serious injuries.

Reason for this proposal

  • Land Transport Rule: Setting of Speed Limits 2022 (the Rule) was notified in the Gazette on 20 April 2022 and came into force on 19 May 2022.
  • Council has adopted Vision Zero as the philosophy for road safety in the city, as an aspiration to achieve zero road deaths and serious injuries within Porirua.
  • The relationship between speed and road crashes is well-established internationally, and managing speed is one pillar of the safe transport system approach
