Prime Minister Helen Clark acknowledged that Labour president Mike Williams had made "a mistake" in not disclosing the $100,000 interest-free loan Mr Glenn made to the party.
She also disclosed that Mr Williams had discussed with her the issue of Mr Glenn being made honorary consul to Monaco. Any such appointment would be decided by Mr Peters.
Labour issued a statement saying Mr Williams had apologised to Helen Clark for the error and repeated its promise that the interest-free loan would be included in its 2008 disclosures to the Electoral Commission.
It said that in response to questions at the time of the New Year honours about Mr Glenn's donations to Labour, Mr Williams "incorrectly said that we had not received any donations from Mr Glenn since the 2005 election".
