Description

Mercury NZ Ltd (Mercury), formerly Mighty River Power Ltd, is an integrated power company which generates, retails, and trades electricity. It produces power from hydro, wind, and geothermal sources. The company operates various power projects in South and North Islands. It retails energy to homes, businesses and industrial customers across the country under GLOBUG and Bosco brands.
