Labour president Moira Coatsworth has hit back at reports wealthy businessman Donghua Liu made large donations to the party, repeating Labour's position that it has no records of them.
In a written statement Coatsworth said several media organisations had reported Liu claims he purchased a book for $15,000 at a Labour Party fundraiser in 2007.
"We have found no records of any such purchase. No-one has provided any documentary evidence to us that contradicts our records," she said.
She said the Herald on Sunday today reported that Liu signed a statement claiming he paid "close to $100,000" for wine at a 2007 Labour Party fundraiser, but it had refused to provide Labour with a copy "or let us read the statement".
"We consider this to be a denial of natural justice," she said.
She said the newspaper disclosed to Labour that Liu's statement claimed the fundraiser was held on June 3, 2007.
"We have found no record of any fundraiser held on that date."
Coatsworth said Labour had not been approached by the Electoral Commission nor any regulatory agency.
"We have always cooperated with regulators, and will always do so when required.
"We continue to call on Donghua Liu and any third parties who might have information about these allegations, including the Prime Minister, to place what they know into the public domain or to refer to the regulators."
