Labour leader David Cunliffe now says his party would make it a priority to get rid of ''coat-tailing" under MMP if it leads the Government after the September election.
He says that within its first 100 days, Labour would remove the coat-tailing provision and lower the MMP threshold required for a party to get MPs without an electorate seats from 5 per cent to 4 per cent.
That was Labour's position to the Electoral Commission which reviewed MMP earlier this term but Mr Cunliffe has moved to harden the position in the wake of the Internet Mana alliance announced last week.
The two parties will stand separately in electorates but have a joint list, meaning that if Mana leader Hone Harawira wins his Te Tai Tokerau seat, and no others, and Internet Mana got about 3 per cent Party Vote, the alliance could get four MPs.
Mr Harawira's Labour opponent is Labour list MP Kelvin Davis.
