KEY POINTS:
Winston Peters yesterday used Parliament to target other MPs as part of his retaliation for questions over his own party's handling of donations.
But he restricted his attacks to a backbench National MP and a former Green Party MP.
Mr Peters attacked National MP Craig Foss, tabling Companies Office records in which Mr Foss was listed as owning 2,524,750 shares in Cynotech Holdings.
Mr Peters questioned why Mr Foss' shareholding was not listed in the Register of Pecuniary Interests in which all MPs are required to declare their financial interests.
In a statement to Parliament, Mr Foss, said the shares were registered in the name of the Foss Family Trust, and this was included in his disclosure of interests.
He also tabled a statement from the share registry confirming the trust had owned the shares - worth about $423,000 at yesterday's prices - since April 2003.
Cynotech is a finance and satellite phones company directed by former Equiticorp boss Allan Hawkins.
Mr Peters' claims follow intense questioning about his own entry in the Register of Pecuniary Interests after revelations that billionaire Owen Glenn had given $100,000 in 2006 to cover Mr Peters' legal bills.
Act leader Rodney Hide has asked the Speaker to consider whether Mr Peters' failure to disclose the gift breaches Parliament's rules.
Mr Peters - who had repeatedly denied getting a donation from Mr Glenn - has claimed he has not broken any rules.
Mr Foss said he was surprised to have been targeted by Mr Peters, and had asked the registry to check why the Companies Office had listed him personally as the shareholder.
Mr Peters, who has come under hard questioning from the Green Party over the donations, also brought up the case of former Green MP Ian Ewen-Street and his partner Sue Grey.
In 2003, Mr Ewen-Street stood down from a select committee inquiry into the scampi industry, citing potential conflict of interest after he began a relationship with Ms Grey, who was a lawyer appearing before it.
Yesterday, Mr Peters described it as "improper behaviour".
