Thursday's papers: Labour going to extraordinary lengths to derail John Key's election campaign and tarnish his reputation; customers being offered incentives to stay with Contact Energy.
The New Zealand Herald says Labour is going to extraordinary lengths to derail John Key's election campaign and uncover his knowledge of a notorious white-collar crime in the 1980s.
The Herald says Labour has now pulled back from what it originally believed was a "neutron bomb" against the National Party leader, but has pushed on with what the paper says is a concerted effort to tarnish his reputation.
The Dominion Post says Labour has been digging through Mr Key's past in attempt to link him to sham currency deals, in what National is labelling a desperate smear campaign.
