Note:
The information from (a) to (e) as disclosed above has been time-weighted to reflect the acquisition of Taupo and Rotorua distribution assets from United Networks. This is calculated by averaging the acquired component of the information in (a) to (e) for the five month period and adding this to data held by the Company for the twelve month period. An example of the time weighting of System Lengths is calculated as follows:

System Lengths Owned by Unison from 1 April to 31 March 03 (A) 4660 km
System Lengths Acquired by from 1 November to 31 March 03 (B) 3366 km
Average System Lengths = A + (B x 365) x 150
Average System Lengths Result (as per (a) above) 6043
