Meridian And NZAS Agree To Shorten Current Demand Response
New Zealands hydro storage is looking much healthier than it was just a few weeks ago, so we are now confident regarding security of supply this winter. As a result, we want NZAS to get back to business, says CEO designate Mike Roan.
Meridian Energy and New Zealand Aluminium Smelters Limited (NZAS) have agreed that NZAS will ramp up production from 16 June 2025 to bring the current demand response to an end early, targeting a completion date of 11 August 2025 rather than 25 November 2025. NZAS will notify Meridian if the target completion date changes.
The demand response option in place is Option 4. This is normally 185MW but currently modified to 50MW.
'New Zealand's hydro storage is looking much healthier than it was just a few weeks ago, so we are now confident regarding security of supply this winter. As a result, we want NZAS to get back to business' says CEO designate Mike Roan.
'This is another example of how willing NZAS is to support New Zealand's electricity system while making some of the purest, renewable aluminium on the planet and we are hugely appreciative of that.'
Meridian will next have the ability to call for demand response Option 3 (100MW) or Option 4 (185MW) under the demand response agreement between the parties to take effect from 12 April 2026. Meridian will next be able to call demand response Option 1 (25MW) no sooner than 60 days after this ramp up finishes, and Option 2 (50MW) no sooner than 90 days after this ramp up finishes.

The Sale Of A Top-Rated Power Company Signals A Shrinking Market
Flick Electric has been named New Zealand's top-rated power company in Consumer NZ's latest energy retailer survey - but the win comes with an unexpected twist. Flick achieved a standout satisfaction score of 71% (very satisfied), earning a People's Choice award. Flick was recently sold to Meridian Energy – the parent company of Powershop, which failed to meet the People's Choice standard in 2025. In contrast to Flick, Powershop, a seven-time People's Choice winner since 2015, has seen a notable drop in satisfaction – from 67% in 2024 to just 60% this year, pushing it out of the top tier for the first time in years. 'Flick has consistently rated well in our surveys, so it's disappointing to see it absorbed by a larger player,' says Jessica Walker, Consumer NZ acting head of research and advocacy. 'Flick customers have been typically among the most satisfied. We don't know what the future holds for Flick customers, but there is a risk it will be consumers who will bear the brunt of reduced competition.' The poorest performers this year are Pulse Energy (41%), Contact Energy (44%) and Mercury (47%). Contact Energy and Mercury are two of the largest energy providers in the country and are known as 'gentailers', electricity companies that both generate and retail electricity directly to households. Meridian Energy was the third-best performing power provider in the survey results and notably the highest-ranking of this country's four gentailers. Frank also earns People's Choice, but sector-wide ambivalence is up Frank Energy joins Flick in receiving a People's Choice award, with 65% of its customers reporting high satisfaction. However, broader trends across the industry point to a decline in overall positivity and a rise in customer ambivalence. 'More people are rating their power providers as 'just OK' rather than great,' says Walker. 'It's a clear sign that satisfaction is softening, and the market isn't delivering the value or the service that New Zealanders expect.' Frank's parent company is also a gentailer, Genesis Energy, which falls into the middle-of-the-pack category. Key findings from the 2025 survey Value for money scores have dipped across much of the sector. Fewer problems were reported. Amongst those who did, there was a slight drop in satisfaction with the retailers' handling of issues. Confidence in the electricity market is low. 36% say it's working poorly for New Zealanders. Signs of hardship are rising. More missed payments, overdue fees, borrowing to pay bills and disconnections. Loyalty won't lower your bill - shop around Walker urged consumers not to stay loyal to underperforming providers. 'Power is the same no matter who you buy it from – but price and service vary widely,' she says. 'There's no reason to stick with an expensive or unhelpful provider.' Powerswitch, Consumer NZ's free and independent power comparison tool, helps people find better plans and providers. On average, people who check power options through Powerswitch can typically save around $500 a year. 'With satisfaction falling and pressure on household budgets rising, take action now,' Walker says. 'More than half a million New Zealand households in the past year alone have used the Powerswitch service. It's quick and easy to switch!' Note: Consumer NZ energy retailer survey data is from a nationally representative survey of 1,985 New Zealanders, aged 18 years and over, carried out in March and April 2025. Satisfaction rating shows the proportion of respondents who scored their retailer 8, 9 or 10 on a scale from 0 (very dissatisfied) to 10 (very satisfied). Ratings are for retailers that had 30 or more responses in our survey. View the results here.

Tiwai Point to ramp up production
Meridian Energy's Manapōuri power station. PHOTO: MERIDIAN ENERGY The Tiwai Point aluminium smelter is ramping back up as hydro lakes further north have received more rain. Meridian Energy said in a statement yesterday that it and New Zealand Aluminium Smelters Limited (NZAS) had agreed NZAS would ramp up production from June 16 to bring the current demand response to an end early, targeting a completion date of August 11. It had been set at November 25 but will now end more than three months earlier than that. NZAS will notify Meridian if the target completion date changes. The demand response option in place is Option 4. This is normally 185MW but has been modified to 50MW. "New Zealand's hydro storage is looking much healthier than it was just a few weeks ago, so we are now confident regarding security of supply this winter. As a result, we want NZAS to get back to business," Meridian Energy chief executive Mike Roan said. "This is another example of how willing NZAS is to support New Zealand's electricity system while making some of the purest, renewable aluminium on the planet and we are hugely appreciative of that." Meridian will next have the ability to call for demand response Option 3 (100MW) or Option 4 (185MW) under the demand response agreement between the parties to take effect from April 12 next year. It will next be able to call demand response Option 1 (25MW) no sooner than 60 days after this ramp up finishes and Option 2 (50MW) no sooner than 90 days after this ramp up finishes. There had been concerns about hydro storage earlier this year. New Zealand's controlled hydro catchments — the main driver to keep the lights on during winter — had had the driest start to the year in 93 years of historic records, a statement from Transpower said in late April. But rain had arrived in the catchments of the hydro lakes and helped to fill them up. Hydro power supplies about 57% of the nation's electricity supply. Minister of Energy Simon Watts earlier announced changes to drawdown limits at Lake Manapōuri and Lake Te Anau. Mr Watts said the changes would deliver an extra 45GWh of energy from the Manapōuri Power Scheme each year — enough energy to power around 6000 homes. It was an important step in the government and the sector's work to protect the security of the country's energy supply for the future, Mr Watts said. — PL

International Visitor Spending On The Up
Press Release – New Zealand Government International Visitor Survey results show for the year ending March 2025, international tourism contributed $12.2 billion to New Zealands economy, up 9.2 per cent compared to the previous year. Minister for Tourism and Hospitality New data showing international visitor spending increased by almost ten per cent on the previous year is welcome news, Tourism and Hospitality Minister Louise Upston says. 'Tourism is our second highest export earner and today's results show just how important the sector is to unleashing economic growth in New Zealand,' Louise Upston says. International Visitor Survey results show for the year ending March 2025, international tourism contributed $12.2 billion to New Zealand's economy, up 9.2 per cent compared to the previous year. This reflects an increase of 4.3 per cent in international visitor arrivals, with 3.32 million visitors coming to New Zealand, up from 3.18 million in 2024. 'In real terms, that means more bookings in our restaurants, more reservations at local accommodation and visitor experience providers, more people visiting our regions and attractions, more jobs being created across the country, and an overall stronger economy.' When adjusted for inflation, this equates international spending to $9.7 billion or 86 per cent of pre-pandemic levels. 'The growth in visitor numbers and spending is very encouraging but there is still more work to do to ensure tourism and hospitality can really thrive,' Louise Upston says. 'Amongst other initiatives, the Government announced a $20.4 million Tourism Boost package this year to help drive visitor numbers. 'New Zealand is open for business, and we look forward to welcoming more visitors to our beautiful country.'
