Auckland-based energy distributor Vector said its net profit fell by 1.3 per cent to $198.8 million in the year to June.
The company said if the impact of a 2011 one-off sale of rights to Transpower was stripped out, then its underlying net profit after tax would have risen by 16.1 per cent to $198.8m.
All Vector's operating segments generated increases in earnings before interest, tax, depreciation and amortisation (EBITDA).
Group EBITDA fell 1.4 per cent to $627.4m from $636.6m.
However, adjusting for the 2011 non-operating $42.4m contribution from the sale to Transpower of rights to use Vector's Penrose-to-Hobson Street tunnel, Vector's underlying group EBITDA rose by 5.6 per cent to $627.4m.
