Prime Minister John Key was on the phone to Pacific Aluminium boss Sandeep Biswas offering him millions of taxpayer dollars to keep the Tiwai Point smelter open, just two days after his ministers largely discarded the idea, Treasury documents show.
The documents released yesterday show Mr Key picked up the phone after Mr Biswas wrote to him seeking "Government involvement", despite Treasury's warnings not to get involved.
The papers detail year-long negotiations between Meridian Energy and Pacific Aluminium over the price of electricity which ended last month when the Government made a $30 million payment to the smelting company.
While Pacific Aluminium - which is largely owned by mining giant Rio Tinto - threatened to close the smelter if it didn't get a lower power price, Treasury repeatedly warned the Government that a direct subsidy to the smelter was not in New Zealand's economic interest.
In March, when Meridian indicated it might leave the negotiations, Cabinet ministers Bill English, Steven Joyce and Tony Ryall agreed they were unlikely to consider direct assistance to the smelter.
