If there was a review of the electoral law, she would like that to be looked at to see if would be justified.
"It's workable at the moment but I think it is worth looking at – whether the Electoral Commission could be powered up a little more in that respect."
Alicia Wright declined to give any details about the commission's inquiry into the New Zealand First Foundation.
"I know there's a lot of public interest but at this point we don't want to speak about that any further," Wright told reporters.
"We've reached out and been provided information from a variety of sources but it is probably best that I leave it at that."
She wouldn't put a timeline on when it should be concluded or say whether she had met with New Zealand First leader Winston Peters.
Committee chair Meka Whaitiri would not allow Nick Smith to ask any questions about the law banning foreign donations over $50 which has just passed under urgency this week and which takes effect from January 1.
But outside the committee Wright said the commission had given advice on the bill, which requires the commission to give advice to party secretaries on how they should check whether donations have originally come from overseas.
She said the commission was intending to get guidance out before Christmas and it would include looking at factors such as whether donors were on the electoral roll or on the companies register.
The New Zealand First Foundation was set up on the model of the National Foundation, according to documents obtained by Stuff.
But the differences are that the National Party declares donations given to it through the foundation as though it were a donation to the party.
