The 5% threshold that parties have to cross to make it into Parliament will be looked at as part of the review of MMP.
The Electoral Commission has announed the timetable for the review which will take place following the 58% vote in favour of retaining MMP in last month's referendum on the voting system.
The commission will call for submissions in mid-February and hold public hearings in April and May before releasing a proposals paper in August for public comment.
A final report will go to the Minister of Justice in October.
Topics that will be looked at include the threshold parties should cross to qualify for list seats in Parliament and whether a person should be able to stand as a candidate in both an electorate seat and on a party list.
