Forget Warner Brothers and The Hobbit. Negotiating with Hollywood moguls must now feel like a bit of a doddle for John Key compared to mixing it with the cold-blooded, razor-wielding gang of cost accountants from Rio Tinto.
The Prime Minister prides himself on his currency trader-derived capacity to cut a deal in the most difficult of circumstances. The stalled negotiations between Meridian Energy and the minerals conglomerate over how much the latter should in future pay for electricity for its Bluff aluminium smelter may provide the ultimate test of his ability to get a result which satisfies everyone and does not leave anyone looking like a big loser.
He did not get off to the greatest start. Last week's Government offer of a "modest" short-term subsidy to bridge the gap between Meridian's best offer and the price Rio Tinto will accept got short shrift from the firm.
The subsidy was the kind of stop-gap compromise that Key often favours and which - in postponing the smelter's day of reckoning - drives his critics to distraction. But - as he argues - National may have been damned for intervening, but it would have been damned even more had it not waded in.
Rio Tinto's rejection of one of the Prime Minister's less elegant solutions was clearly predicated on its goal of a cheap deal over the long term - something it believes it can achieve because it senses it has the Government over a barrel.
