Performance Measures

We monitor performance measures and reports on them on a regular basis. The purpose of these measures is to track the performance of:

• the Gas (Switching Arrangements) Rules 2008 (the Switching Rules)
• the Gas (Downstream Reconciliation) Rules 2009 (the Reconciliation Rules)
• the Gas Governance (Critical Contingency Management) Regulations 2008 (CCM Regulations).

We do this review both in terms of activity related to these statutes and the competitive outcomes that they foster.

The Report also tracks transmission balancing actions, as a means of informing our work on this issue.

The 2020 Performance Measures Quarterly Report can be found under Related documents.

Updates from the June 2020 Report include:  

• As a result of the COVID-19 Alert Level 4 lockdown, switches in April 2020 fell to the lowest level since the Switching Rules commenced in 2009. They recovered in the remainder of the quarter, after the lockdown was lifted.
• There are 12 distinct retail brands, owned by 10 parent companies. During the quarter Scholarship NZ and EnergyClub NZ exited the gas market.
• In the past 12 months, there have been about 3,400 not withdrawn switches completed per month, which translates to an annual churn rate of about 14.2 percent.
• Over 75 percent of consumer switches are completed within three business days; 97 percent are completed within seven business days.
• Over 99.8 percent of gas customers are connected to a gate where seven or more retailers trade, suggesting that the gas retail sector is generally competitive throughout the North Island.
• Average annual unaccounted-for gas (UFG) over the past year stands at about 1.1 percent (compared with about 2 percent in 2009).
• Genesis is the largest retailer by customer share. Nova has the largest share of commercial and industrial customers.
• Nova is the largest retailer by volume market share.
• Monthly traded volumes on emsTradepoint reached a peak of 1,125 TJ in February 2020.
