I initially signed up with Mercury…

I initially signed up with Mercury mid-last year for electricity, gas, and Wi-Fi, expecting a seamless experience. However, I was disappointed to find hidden costs and rising bills, which led me to cancel my electricity and gas services with them recently. The exit fees were a significant surprise, and I'm now working to pay off the outstanding balance.On the positive side, the Wi-Fi service has been decent, and the extender they provided has been working well. However, I'm not happy about the overall experience and the financial burden of paying off the old bill while still covering my monthly Wi-Fi fees. If you're considering Mercury, I'd advise being cautious and carefully reviewing the terms and conditions. Maybe it was just a bad experience, but I wouldn't recommend them to anyone looking for a hassle-free service.

Business Details

  • At Mercury we’re thinking boldly about the possibilities with energy and inspiring New Zealanders with our clean, green electricity and ideas – making energy wonderful. Renewable energy from Mercury’s hydro and geothermal stations will power a brighter future for our country.

    We have a long heritage in renewable energy in New Zealand serving about 1-in-5 homes and businesses under the Mercury brand and other specialty brands, including the leading pre-pay product GLOBUG. Mercury also has proven capability and technical expertise in smart metering services and solar.

    Our electricity generation is 100% renewable, with the hydro and geothermal power stations operated by Mercury producing enough renewable electricity for about 1 million New Zealand homes. The nine hydro stations dating back to the 1920s make up the Waikato River Hydro System, accounting for about 10% of the country’s total electricity supply that is predominantly hydro.

    Mercury led a renaissance in geothermal energy over the past decade with an innovative investment programme in partnership with local Maori landowners, enabling the completion of three major geothermal projects in 2008 (Kawerau), 2010 (Nga Awa Purua) and 2013 (Ngatamariki). These sustainably harness natural heat deep underground, producing steady ‘base-load’ electricity – normally running 24/7 and are not dependent on the weather like other forms of renewable generation.

    We have established a leadership position in encouraging the electrification of transport, supporting the adoption of e-bikes and electric vehicles, partnering on charging infrastructure and moving 70% of the company’s vehicle fleet to plug-ins by 2018.See more
