Former MP Taito Philip Field is to lose his travel entitlements following his conviction on bribery and obstruction of justice charges.
Parliament's Speaker of the House says from now on, conviction of a serious offence committed while an MP will disqualify that person from the travel entitlements available to former MPs.
Lockwood Smith says if he did not change the rules Field would have continued to get heavily subsidised travel, despite being convicted of offences he committed while an MP.
Field's wife will also lose her entitlements to subsidised travel.
Dr Smith says an amendment will be made to the Speaker's directions and should take effect from October this year.
The decision applies to the travel entitlements only available to former MPs who entered Parliament before 1999.
In August, a jury found Field guilty of several counts of bribery and obstruction of justice. He will be sentenced in October.
