Mercury is primarily a generator and retailer of electricity, focussed on meeting the energy needs of New Zealanders. Our mission is Energy Freedom for all New Zealanders. This is about Aotearoa New Zealand being stronger economically and more sustainable through better use of homegrown, renewable energy.
We generate electricity from 100% renewable sources: hydro, geothermal and soon, wind, at our wind farm at Turitea, Manawatu. In 2021, Mercury announced it will acquire all of Tilt’s New Zealand operations, including development options, subject to relevant approvals.
Our retail operations serve residential, commercial (small and medium sized businesses), industrial and spot market customers. We also offer prepay electricity through our GLOBUG brand. We manage a small number of subsidiary enterprises such as Mercury Drive (an exploratory electric vehicle by subscription service).
We support our people to be high performers through a commitment to wellbeing, inclusion and development. Our mission of Energy Freedom is pursued in many ways, including through the electrification of transport, which we see as New Zealand’s greatest opportunity for reducing carbon emissions. We encourage the adoption of electric vehicles (EVs) and electric bikes (e.bikes) and partnering on non-home charging infrastructure and data. Our purpose is to inspire New Zealanders to enjoy energy in more wonderful ways. We do this by championing e.transport, providing offers to our loyal customers and innovating with digital solutions to make interactions with us easy and rewarding.
