The Greens yesterday reallocated policy portfolios among the party's six MPs.
The Green caucus has been reduced from nine to six following last month's election.
Greens co-leader Rod Donald said there had been some reshuffling and reallocation of responsibilities previously covered by the departed MPs.
"While all MPs have anincreased workload, second-term MP Metiria Turei has picked up significant new responsibilities including justice, conservation and biosecurity," Mr Donald said.
The justice spokesmanship was held by Nandor Tanczos, who was too far down the party list to make it back into Parliament.
