Vector has lifted its half year profit as customer numbers grow.
The energy and communications company made $105.3 million in profit in the six months to December, 7% more than the $98.5 million the previous year.
Revenue grew 0.8% to $634.3 million. Electricity volumes edged up 1.4%, while earnings in its wholesale gas division rose almost 15% because of an increase in natural gas.
Group chief executive Simon Mackenzie says there has been steady growth in electricity sales in the past two years, and it has also signed more wholesale customers.
Vector will pay a dividend of seven cents per share, up on the 6.75 cents paid last year.
