All SAIDI, SAIFI and CAIDI figures have been calculated from average, rather than year end, consumer numbers.
This is the methodology prescribed in the Commerce Act (Electricity Industry Distribution Threshold) Notice 2004.
Prior years figures have been restated in accord with that method although the changes are not material.
