Maramarua mine


Maramarua is an opencast mine located in the Waikato region of New Zealand producing a low-ash, low sulphur thermal coal for the domestic market.

Maramarua has a long history of coal mining with an opencast mine first being developed at the site in 1948. It has been mined in modest quantities since that time.

The coal produced at Maramarua has a low sulphur and ash content, making it ideal for steel production. The biggest customers for Maramarua’s coal are local dairy plants and a steel mill.

Successful production at Maramarua comes from a favourable mining environment and well-equipped infrastructure. 

Due to the Resource Management (National Environmental Standards for Freshwater) Regulations Act, the M1 pit design has been modified to preserve areas identified as inland natural wetlands. A new resource consent application was submitted, and iwi and stakeholder consultation is well advanced.

The project is scheduled to start in FY23 on approval of consents, with the coal destined for the same customers as current operations.
