Hoteliers Earl and Lani Hagaman are seeking up to $2 million in damages from Labour leader Andrew Little in a defamation suit against him.
The trial started today at the High Court in Wellington.
The Hagamans' lawyer Richard Fowler said Earl and Lani Hagaman claimed Little had repeatedly defamed them in a press release and six media interviews he did last year about a $100,000 donation from the Hagamans to the National Party in 2014 and a contract awarded to their hotel chain, Scenic Hotel, to manage the Matavai resort in Niue.
Fowler said the Hagamans claim was that the comments by Little amounted to an "inference of corruption".
The lawyer pointed to six examples, a press release and five media interviews, in which Little had questioned whether there was a link between the donation and the Matavai contract which was awarded to Scenic Hotel soon afterward.
He also queried a $7.5 million Government aid fund to upgrade the resort at a later date, money Fowler said went to the trust which owned the hotel rather than Scenic Hotel.
Fowler said Little's comments included phrases about the timing: "it looks murky from the outside, it looks shady," "stink to high heaven," "there's just something about this whole deal that really stinks" and reference to National Party's "dodgy deals" such as an agrihub in Saudi Arabia.
"The Hagamans say the fundamental theme is one of corruption," Fowler said.
