The former Deputy Prime Minister Winston Peters is planning to seek a judicial review of the decision to trespass him from Parliament.
The New Zealand First leader is among several high-profile people who have been issued with trespass notices after attending February's anti-mandate protest.
Mr Peters says he wants to seek a precedent on behalf others who were trespassed from Parliament's grounds for peacefully protesting.
Meanwhile, the ACT party is the sole party in Parliament that thinks former MPs should be exempt from attempts to trespass.
The party's leader David Seymour spoke to Māni Dunlop.
