Meridian Energy reported record full-year earnings, boosted by higher power prices and generation volumes and a growing customer book in Australia.
The country's biggest electricity generator said net profit jumped 68 per cent to a record $339 million in the year ended June 30.
Earnings before interest, tax, depreciation and changes in financial instruments rose 26 per cent to $838m, also a record.
"The results reflect a record level of hydro generation in New Zealand, and higher wholesale prices as a result of supply interruptions at the Pohokura gas field, and periods of low hydro inflows," chief executive Neal Barclay said in a statement.
The performance enabled the company to lift total dividends to the government and shareholders by 11 per cent, while overseeing a decrease in average energy prices for households and small businesses, he said.
