Labour leader Andrew Little has nominated Winston Peters for an important Parliamentary role that has oversight of the spy agencies.
Mr Little wants Mr Peters to join the Intelligence and Security Committee which assess the work of the GCSB and SIS, replacing David Shearer, who has left Parliament.
The nomination is backed by the Greens - but will have to be signed off by the Government.
"As a former Foreign Affairs Minister, Winston has extensive experience of New Zealand's security and intelligence agencies and so would be a valuable addition to the committee," Mr Little said.
"There are currently only two places on the five-member Intelligence and Security Committee for Opposition MPs. I do not believe that fairly reflects the proportionality of Parliament.
"The committee should be enlarged to accommodate other Opposition parties with significant representation in Parliament."
"We are talking with the Government about this, and I will be tabling a Supplementary Order Paper to this effect when the Intelligence and Security Bill is reported back to Parliament shortly."
