- Meridian's total electricity generation for April was 1,009 GWh, up 13.5% on last year, reflecting strong hydro conditions.

What else do investors need to know?
April's bumper rainfall in the North Island and healthy inflows in the South Island boosted hydro storage across the country. Meridian's Waitaki catchment ended April at 106% of average storage, while Waiau reached 91%.
Retail customer connections dipped by 1.1% in April, but still grew 15.7% over the year. Retail segment sales outpaced 2025 levels for every major customer group, with business and agricultural segments both seeing solid growth.
On the wholesale market, ASX forward electricity prices continued to fall, likely reflecting strong renewable investment and improved system security from Huntly agreements.
What's next for Meridian Energy?
Management is staying focused on capitalising on strong hydro conditions as New Zealand moves into winter, traditionally a period of higher demand. Meridian is also watching market dynamics as increased renewable generation investment and strong storage keep prices subdued, which could impact earnings going forward.
