The company is based in New Zealand and is regulated by the Electricity Authority and the Commerce Commission.

Common questions

The Selectra expert answers your questions about Slingshot

Slingshot is one of New Zealand's licensed electricity retailers, regulated by the Electricity Authority. Whether it is the right fit for your household depends on your usage profile, region, and the rates available on the plans listed above. Always compare your quoted price against several other retailers based on your address and 12-month consumption before you switch.

Switching to Slingshot is usually completed within a few days, up to a regulated maximum of 10 working days, and your power supply is never interrupted. Sign up online with your address and ICP number (printed on any past power bill). Slingshot will handle the transfer with your current retailer, including the final reading.

New Zealand consistently runs one of the greenest grids in the OECD: around 80% to 90% of grid electricity comes from renewable sources (hydro, geothermal, wind), with recent full-year figures sitting above 85% and individual quarters occasionally exceeding 95%. Some retailers (notably Mercury and Meridian) market themselves as 100% renewable. Check the plan badges above — offers tagged green energy are sold as renewable-only.

Most NZ electricity plans have no exit fees on open-term contracts. Fixed-term plans may include a break fee if you switch before the term ends. The "Exit fees" line on each plan card above shows the current policy.
