¹ Improved information has resulted in Vector reviewing its system lengths for 2004. As a result, the system length and the relevant performance measures and statistics have been restated.
² The 2003 performance statistics have been calculated using a time-weighted average in accordance with the Electricity (Information Disclosure) Regulations 2000, Regulation 33. Vector Limited was combined with UnitedNetworks Limited in October 2002. One month (October 2002) includes the Eastern region of UnitedNetworks Limited as well as the Northern and Wellington regions. The final 5 months are for Vector Limited, plus the Northern and Wellington regions of UnitedNetworks Limited.
