The 2008 Government Policy Statement on Gas Governance requires the industry to have sound arrangements for the management of critical contingencies. This provision is met through the Gas Governance (Critical Contingency Management) Regulations 2008 (CCM Regulations), which set out how industry participants plan for, and respond to, a serious incident affecting gas supply via the gas transmission pipelines.

The purpose of the CCM Regulations is to achieve the effective management of critical gas outages and other security of supply contingencies without compromising long-term security of supply.

The CCM Regulations came into force on 21 January 2010. They were again reviewed following an extended supply disruption on the Maui Pipeline in 2011. Amendments strengthening and clarifying aspects of the regulatory arrangements took effect on 1 March 2014.


The Current Arrangements section contains information on the following:

  • CCM Regulations and related arrangements
  • Critical Contingency Operator
  • Regional/Non-regional Guidelines
  • Critical Contingency Management Plans
  • Determinations
  • Market Fees
  • Contingency Designation Applications
  • Information for Consumers regarding Critical Contingency Events

The Critical Contingency Events section contains information on critical contingency incidents. The most recent critical contingency caused by a system imbalance at the Kapuni Gas Treatment Plant occurred on 23 May 2017.

The Background section contains historical information on the Regulations review (2012 - 13), and it's original development (2006 - 08).

Below you will find the CCM Regulations.
