Electricity Rates in Oceania (2026): NZ vs Australia and the Pacific

Electricity prices in Oceania (2026), ranked

Power prices across Oceania stretch more than fivefold from cheapest to most expensive. New Zealand and Australia run liberalised, mostly-renewable grids with stable tariffs, while smaller Pacific nations stay locked into imported diesel and difficult small-island logistics. Every price below is in NZD per kWh.

Methodology: Selectra-collected residential profile (5 kVA, 300th kWh in capital city) for NZ, AU and PG, converted EUR to NZD at the day rate. Pacific-island ranges come from national regulators and utility tariff schedules. Last update: 28 May 2026.

New Zealand: clean-energy heavyweight, moderate prices

0.34 NZD/kWh

New Zealand runs one of the cleanest grids on the planet. Roughly 85 % of every kilowatt-hour is renewable, powered chiefly by hydropower, geothermal and wind. That clean stack pays off on reliability too: average annual outages stay under 2 hours per customer.

Households pay around 0.34 NZD/kWh, with 25 to 30 % of the bill funding transmission, distribution and infrastructure levies. Competitive generation and retail, plus tough regulatory oversight, keep wild price spikes off the table. Time-of-use tariffs and the smart-meter rollout are now turbo-charging rooftop solar and home batteries nationwide.

Australia: hyper-competitive market, big price swings

0.36 NZD/kWh

Australia runs one of the planet’s biggest interconnected grids, the National Electricity Market (NEM). The average household pays roughly 0.36 NZD/kWh, about 3.0 % more than New Zealand.

Even with vast coal, gas and solar resources, Aussie prices react fast to export trends, commodity spikes and summer heatwave demand. The pivot away from coal toward renewables and grid-scale batteries has triggered heavy network reinforcement, pushing fixed charges up. The upside: shoppers enjoy aggressive retail competition and some of the world’s most generous solar feed-in tariffs.

Papua New Guinea: abundant resources, scarce access

0.32 NZD/kWh

Papua New Guinea (PNG) posts one of the lowest published tariffs in the Pacific, roughly 0.32 NZD/kWh. The catch: only 15 to 20 % of the population is wired into the national grid in the first place.

Hydropower fuels most urban electricity, while remote regions still lean on small diesel sets or private generators. The Electricity Industry Policy sets a bold target: 70 % national access by 2030, fuelled by rural electrification and renewable microgrids.

Fiji: regulated, renewable-led, regional value pick

0.23–0.25 NZD/kWh

Fiji’s tariffs average just 0.23 to 0.25 NZD/kWh, among the friendliest in the Pacific. Hydropower carries most of the load, backed by diesel and a fast-rising share of solar. Cities like Suva enjoy rock-steady service, while outer islands still lean on diesel microgrids.

The Fiji Electricity Authority (EFL) sets retail prices and protects low-income households with subsidised "lifeline" tariffs. The government is pushing hard for 100 % renewable generation by 2036, locking the country away from imported-fuel shocks.

Vanuatu: pricey power on borrowed barrels

0.80 NZD/kWh

Vanuatu carries some of Oceania’s steepest electricity costs, averaging around 0.80 NZD/kWh. Over 70 % of generation runs on imported diesel, so every twitch in global oil markets and freight rates hits household bills.

A small, dispersed population and unforgiving logistics push per-unit generation and delivery costs sky-high. World Bank and Green Climate Fund programmes are bankrolling small-scale solar-hybrid systems across rural areas, though grid reliability is still patchy.

Solomon Islands: highest tariffs, lowest reliability

1.10 NZD/kWh

Electricity in the Solomon Islands lands at around 1.10 NZD/kWh, putting it among the world’s most expensive. A tiny customer base plus near-total dependence on imported diesel keeps prices stratospheric, and only a fraction of the population enjoys grid access.

Government and donor partners are pouring funds into hydropower and solar generation to drag costs back down and shore up reliability. The flagship Tina River Hydropower Project alone is expected to slash prices by up to 30 % once it goes live.

Samoa: steady march to 100 % renewable

0.35 NZD/kWh

Samoan households pay roughly 0.35 NZD/kWh on average. Hydropower already shoulders a chunk of the load, with solar projects funded through international partnerships filling in the rest.

The national goal of 100 % renewable electricity by 2030 is fuelling heavy investment in distributed solar and battery storage. Reliability has stepped up sharply on the main islands, though smaller communities still see periodic disruptions.

Tonga: diesel-dependent, price-sensitive

0.40–0.50 NZD/kWh

Tonga’s energy sector runs almost entirely on imported diesel, making electricity one of the most expensive essentials in the country. Estimates land between 0.40 and 0.50 NZD/kWh.

Tonga Power Limited is rolling out a renewable-energy roadmap aiming for 50 % solar by 2030. Until that transition matures, every global oil-price spike still lands directly on consumer bills.

New Caledonia: heavy industry sets the price

0.30–0.35 NZD/kWh

New Caledonia’s grid revolves around big industrial consumers, especially nickel smelters that gobble up over two-thirds of total demand. Households end up paying an estimated 0.30 to 0.35 NZD/kWh.

Reliability is solid thanks to robust infrastructure, but heavy fossil-fuel dependence and steep fixed costs keep prices elevated. Recent policy is now pushing renewables harder and shielding residential consumers from industrial pricing pressure.

French Polynesia: high cost, strong safety net

0.40–0.50 NZD/kWh

Electricity in French Polynesia averages 0.40 to 0.50 NZD/kWh, pushed up by geographic isolation and diesel imports. Service stays steady thanks to tight grid management and government subsidies that absorb the worst of the cost.

The power sector is shifting gradually toward renewables, with solar and biofuel projects rolling out across the major islands. The administration is targeting a halving of fossil-fuel dependence by 2035.

Oceania’s outlook: a cleaner, more reliable power future

Across Oceania, power markets split sharply between developed and developing island economies. New Zealand and Australia run reliable, well-regulated systems that lean ever more on renewables. Smaller Pacific states still wrestle with high costs, brutal logistics and a heavy diesel-import habit that crushes affordability.

The cheapest published electricity in Oceania lives in Papua New Guinea and Fiji, while Vanuatu and the Solomon Islands sit among the world’s most expensive markets. Backed by the Asian Development Bank and the Pacific Power Association, regional initiatives are now accelerating renewable rollouts, microgrid expansion and serious energy-efficiency programmes.
