Labour leader David Cunliffe has confirmed he used a trust to deal with donations to his leadership campaign in last year's run-off for Labour's top job.
Yesterday Mr Cunliffe refused to say whether a trust was used or whether he had declared donations in the Register of Pecuniary Interests as from a trust or from the original donors.
Labour's rules had stipulated donations to the leadership contenders would remain confidential.
However, the Register for Pecuniary Interests requires all donations of more than $500 to be disclosed in MPs' entries.
Mr Cunliffe said today the rules for the two were "slightly different".
"My advice is that we've met both. We did use a trust, the campaign used a trust and I'm happy to be open about that."
