The furore has already changed the political landscape with National ruling out working with NZ First after the election -- which puts the Maori Party in a more powerful position.
In the immediate future the Electoral Commission will discuss what to do about New Zealand First's alleged breach of electoral law.
On Friday the commission got a letter from the party about its donation returns for 2005, 2006, and 2007. The commission would not give details but it is likely the party was seeking to fix up incorrect declarations.
This development has followed a series of revelations including one from one of the party's Spencer Trust trustees, Grant Currie, who said NZ First got $150,000 of donations, channelled through the trust, in 2005, 2006 and 2007.
NZ First last week admitted breaching electoral law by failing to declare a $50,000 donation from the Spencer Trust in 2005. A further $17,000 in bills was paid in 2005 and the trust also directly paid $87,648 of NZ First invoices in 2006.
An $80,000 donation from the trust to the party in 2007 went towards meeting the party's wrongful spending under the 2005 election. Other parties returned the money to Parliamentary Services but NZ First said it gave it to charity. Police are considering whether to investigate the non-declaration of the donation after ACT's Rodney Hide lodged a complaint.
Under the Electoral Act all donations above $10,000 must be declared but NZ First declared getting no donations over that level in the past three years.
NZ First donations were already being investigated by the Serious Fraud Office, while Parliament's privileges committee is looking at whether NZ First leader Winston Peters broke Parliament's rules by failing to declare a $100,000 contribution from Mr Glenn towards his legal fees.
Mr Glenn is to appear in person on Tuesday to defend his claim that Mr Peters asked and thanked him for the donation.
Mr Peters says that isn't true and he will speak to the committee directly after Mr Glenn. He maintained previously that he knew nothing about the donation.
The swirling allegations prompted National leader John Key to rule out working with NZ First after the election.
That has seen interest in the Maori Party intensify.
Labour Cabinet MP Shane Jones was asked about the situation on Agenda on TV One today.
He said it was up to voters whether NZ First was back as a force after the election.
"They'll make a moral perception as to whether or not this is just a whole lot of administrative drama or whether or not there's some other problem at stake."
Labour would put "fire hydrant pressure" on the Maori Party if any of its MPs indicated working with National.
He said National would scrap the Maori seats and the foreshore and seabed was no longer such a sore point.
Mr Jones said some Maori voted for the Tariana Turia-Pita Sharples-led party out of a sense of rangatiratanga or self-determination. However he said only through a large party would their voice have impact.
"What we're always reminding our people is that it's your vote but do not squander your vote on a party that may be just yapping on the sidelines and Labour from our perspective offers an opportunity to be right in the engine house."
He dismissed a comment from Maori MP Hone Harawira that Labour was a coalition corpse saying his capacity for "alliteration is inversely related to his comprehension of the facts".
Mr Jones said Mrs Turia and Mr Sharples were the ones with the power. He described Mrs Turia as a seasoned politician who would keep her options open.
