New Zealand First leader Winston Peters has welcomed a parliamentary inquiry into a donation he received from Owen Glenn.
A complaint about the donation of $100,000 from the Monaco-based businessman to Mr Peters has been referred to Parliament's Privileges Committee by Speaker Margaret Wilson.
ACT Party leader Rodney Hide says the committee will meet on Thursday morning to set its terms of reference, and he expects the hearing to be open to the public.
Mr Peters initially denied receiving any money from Mr Glenn, but later admitted it went towards the costs of an electoral petition in 2006 after being advised by his lawyer.
He did not declare the donation on a register of pecuniary interests.
Mr Peters says he welcomes the opportunity to set out the facts in the "clear light of day".
Mr Peters also dismissed allegations published in The Dominion Post newspaper on Wednesday that he received donations from Simunovich Fisheries as "drivel".
Mr Peters, who has always denied such a claim, made the response in Parliament on Wednesday.
Mr Glenn was the Labour Party's largest single donor at the 2005 election.
