New Zealand First representation for Tauranga will now be shared by leader Winston Peters and the party's other MPs after the expulsion of Brendan Horan.
Mr Peters announced the former Tauranga list MP's expulsion last week after allegations surrounding money missing from his dead mother's estate.
Mr Horan did not respond to calls from the Bay of Plenty Times yesterday but told One News he asked police to investigate the leak of documents, including phone records detailing his calls to the TAB.
The records showed more than 100 calls to the TAB in a 10-month period.
Mr Horan said that he did not have a gambling problem, that he had done nothing wrong and that he planned to continue as an independent MP.
