The company will pay an 8 cents per share final dividend on October 6, an increase from last year's 6.6 cents, taking total distributions in the current financial year to 16 cents, compared with 13 cents in the previous financial year.
That equates to 80.9 per cent of free cash flow, compared with 80.4 percent the previous year.
Free cash flow at $197.7 million was 22 per cent higher than the previous year.

Falling global oil prices saw returns from Genesis's 31 percent interest in the Kupe oil and gas field fall, with the oil and gas segment of operations showing a 13 per cent drop in Ebitdaf to $93.5 million, with Kupe contributing 27 per cent of Ebitdaf in the latest year, compared with 35 per cent the previous year.
Improved cost-to-serve ratios saw the 'customer experience' segment improve Ebitdaf earnings by $4.7 million to $87.2 million, while the energy management segment, which measures the company's wholesale electricity generation operations, showed a $32.2 million improvement, up 19 per cent on the previous year, at $201.1 million.
Contributors to that result were a 4 per cent increase in total electricity generated to 6,698 Gigawatt hours, and a 7 per cent improvement in the average price received for wholesale electricity, at $75.41 per Megawatt hour.
Total electricity, gas and LPG customers slipped 2 percent to 636,676.
Genesis used 31 per cent more coal and 5 per cent less gas on electricity production during the year.
