The issue of whether MP Brendan Horan should resign from Parliament now his party has expelled him could be part of the legitimate public "conversation" on a wide range of issues relevant to New Zealand's constitutional arrangements.
The Government-appointed advisory panel on constitutional issues will today launch a public consultation process at Te Papa in Wellington.
One of the issues under discussion is electoral integrity legislation - also known as party-hopping law - and whether MPs that leave parties from which they were elected can continue to remain in Parliament.
Mr Horan was expelled from New Zealand First and now sits as an independent MP, depriving New Zealand First of its full representation.
The Labour Government of 2001 passed legislation allowing party leaders to effectively force the resignation of MPs considered to have left the party after a rash of party-hopping and splits in New Zealand First and the Alliance discredited Parliament. But the law had an expiry date, and ran only until the 2005 election.
