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. 

The M1 extension project is at the feasibility stage. It is located within the same permit as the existing mine site, and has the same coal product and is intended for the same customer mix as current operations. Commercial negotiations with key customers are close to complete. Applications for consents were submitted in FY21, with final project approval primarily reliant on granting of the consents.
