“In energy terms it involves the downgrading of a superior and non-renewable energy. Rather New Zealand should explore the many opportunities, both domestically and internationally, to sell gas ‘as is’ or with value added, such as in LPG, CNG or gas to methanol,” Mr Copeland said.

He also indicated that he was “not opposed” to coal-powered electricity generation.

Mr Copeland, who has previously held senior positions in the oil industry, said that he had been disappointed that previous National and Labour conservation ministers had ruled out hydro schemes from “day one”, opting instead to use gas.

“In my view hydro schemes can, with good planning, preserve or enhance conservation values and they need not be viewed as mutually exclusive.

“Wind and hydro generation and the use of solar power are perpetually renewable, and United Future will wholeheartedly support the fast-tracking of such schemes to fill the vacuum which will arise as the Maui gas supply comes to an end,” he said.
