Infrastructure is a critical element of a city’s framework.
It encompasses the infrastructure lifeline networks and hubs: including transportation, (road and highway networks, railways, mass transit systems and transport terminals), energy networks (power networks, generation plants and the electricity grid and other forms of energy generation), water (including drinking, stormwater and waste water) and telecommunications networks (including land and mobile phones, internet, radio and television).
Infrastructure enables people to live in their homes and in their chosen environment, interact with each other, to move around, to do business and to play. It helps to define the city’s urban form and contributes to productivity growth.
The repair of greater Christchurch’s water and road networks is one of the largest and most complex civil engineering projects ever undertaken in New Zealand and will take several years.
The way that central and local government plan and invest in infrastructure development has been significantly impacted by the earthquakes. It is necessary to start with a review of pre-existing infrastructure investment plans and assumptions, risks and opportunities and then to assess both the effects of post-earthquake policy decisions (about where, when and how we can rebuild) and to assess damage reports. This needs to be done in order to identify risks and opportunities, and to identify what needs to be done to effect a timely and coordinated repair, replacement and wherever possible enhancement of the infrastructure in order to get back on track for normal infrastructure development.
Objectives of the programme
- Lead the repair and rebuild of the infrastructure networks
- Evaluate and identify existing infrastructure programmes that are still appropriate; and required to achieve the recovery and longer-term growth of greater Christchurch;
- Coordinate and sequence an infrastructure roll-out that prioritises infrastructure projects and initiatives across both central and local government;
- Identify opportunities to enhance infrastructure networks and provide greater confidence for asset owners throughout greater Christchurch.
Identify and reconfirm existing infrastructure programmes that are still appropriate and required to achieve the recovery and longer-term growth of greater Christchurch. Rethinking the placement and function of assets across greater Christchurch may provide opportunities to enhance infrastructure networks as part of the recovery.
Transportation solutions for recovery issues, such as the changing needs for public transport and the reinstatement and repair of damaged infrastructure will be progressed. The initiative will also identify opportunities to improve the resilience and sustainability of the transport system. Opportunities to improve the transport infrastructure will be considered, with the potential to facilitate more walking, cycling, public transport and freight. Existing transport planning programmes are being considered and integrated by the UDS partners and CERA to ensure the transport network operates seamlessly in the post- earthquake environment.

Horizontal infrastructure repair and rebuild work will be ongoing throughout the city for several years.
- The Stronger Christchurch Infrastructure Rebuild Team (SCIRT) is repairing the city’s roads, water supply, storm water, and wastewater systems that were damaged by the earthquakes. The SCIRT project is one of the largest and most complex civil engineering projects ever undertaken in New Zealand. SCIRT is an alliance of Christchurch City Council, CERA, New Zealand Transport Agency, City Care, Downer, Fletcher Construction, Fulton Hogan, and MacDow New Zealand.
- Commercial infrastructure providers such as Orion, Telecom and Vodafone are rebuilding telecommunications and energy infrastructure systems. CERA and SCIRT will liaise with these providers to align and coordinate repairs where possible to minimise disruption.
The SCIRT website provides news and schedules of work in your area as well as more information on the assessment of damage.
Non-SCIRT Rebuild activities (energy and telecommunications) will be monitored and reviewed to provide a timely and sequenced repair across all networks.
Infrastructure standards and specifications will be reviewed to ensure they are fit for the new seismically active environment and represent value for money.
A decision support tool to decide how the infrastructure rollout will be prioritised will be developed by SCIRT. This will specify what infrastructure will be repaired, where, and when. Priority will be given to what is best from an engineering viewpoint, while taking into account efficiency and community needs. Other influences such as continuing services important to the local economy will also be considered. Coordinating the sequencing and timing of infrastructure projects across service and utility providers will help them line up replacement or repair works and apply the “dig once and dig right” principle. The decision support tool will be reviewed periodically to ensure it remains fit for purpose.
Communications of network infrastructure rollouts including the delivery of the SCIRT programme will be developed.
