The Government's controversial asset sales legislation will come up for its second reading in parliament on Thursday, Prime Minister John Key has confirmed.
It has to be passed before 49 percent of the shares in four state-owned energy companies can be sold and opposition parties are fighting it all the way.
The bill was reported back by a select committee last week, a month before deadline, with hardly any changes.
Labour and the Greens say National MPs used their majority on the committee to bulldoze it through, ignoring hundreds of submitters who called for it to be scrapped.
Shares in Mighty River Power, Genesis Energy, Meridian Energy and Solid Energy are going to be floated, starting in August.
