Labour says it has no record of receiving money from the businessman and National Party donor surrounded in controversy.
The Herald yesterday revealed that Donghua Liu - who received citizenship after lobbying from National minister Maurice Williamson - also paid $15,000 at a Labour Party auction in 2007 for a book signed by Helen Clark, the Prime Minister at the time.
Labour leader David Cunliffe yesterday also said Liu may have made another donation through the purchase of a bottle of wine. However, he was only aware of Liu's potential donations through media reports.
Labour general secretary Tim Barnett said a check of the party's records showed no donation from Liu under his name.
However he said it was possible he made donations via a company or family trust, which was allowed under electoral finance rules at the time, or that donations were made at the local electorate level, details of which were not recorded by the party's central administration.
Former Labour Government Internal Affairs Minister Rick Barker, who attended a dinner in China as a guest of Liu in 2007, yesterday said it was possible Liu made a donation through the purchase of one of several auctioned bottles of wine.
