Best Power Companies NZ 2026
1. Electric Kiwi — Best for Value & Innovation
Electric Kiwi is an independent retailer that has consistently offered competitive pricing alongside its distinctive “Hour of Power” feature — one free hour of electricity per day during off-peak times.
Why it stands out:

Why it stands out:
- Potentially the cheapest option for flexible households

- Fixed-fee model for retailer costs rather than a markup buried in the unit rate
- Shift-and-save: use appliances during cheap overnight or off-peak periods

Watch out for: Price spikes during peak demand or dry years when hydro lakes are low.

Why it stands out:
- No credit checks or bond required

How to Find the Cheapest Power Company for Your Address
Electricity pricing is hyperlocal — the cheapest retailer in Auckland may not be the cheapest in Wellington or Christchurch. This is because:
- Line company charges vary — each region has a different lines company (Vector in Auckland, Wellington Electricity, Orion in Christchurch etc.) and their charges are passed through to your bill
- Some retailers focus on specific regions — Nova Energy competes harder in the North Island, for example
- Your usage matters — high-usage households benefit from lower unit rates; low-usage households often benefit from lower daily charges
