Note: The last two performance measures are not required by the Gas (Information Disclosure) Regulations 1997.

1. The increase in percentage is due to the revaluation carried out during the year and the reversal of the subvention payment.

2. The increase in Unplanned Distribution System Interruptions not related to Transmission System Interruptions was due to water inundation outage in St Johns Hill Wanganui in late June 2010. This single significant event was caused by a leaking water pipe and contributed 0.225 hours/customer. Without that event the measure would have been 0.0296.

3. The decrease is due to there being no significant interruptions to the network during 2010/2011.
