VANCOUVER, BRITISH COLUMBIA—(Marketwire – Nov. 14, 2012) – Methanex Corporation (TSX:MX)(NASDAQ:MEOH)(SANTIAGO:Methanex) announced today that it has secured further gas supplies in New Zealand.

We are continuing to work with suppliers and are optimistic that we will be able to secure more gas to underpin the restart of the Waitara Valley Plant next year.”
