Legislation the Government must pass so it can partially sell state-owned assets is being rushed through Parliament, opposition parties say.
The select committee dealing with the Mixed Ownership Model Bill is going to report it back next week, well ahead of its July 16 deadline.
Labour and the Greens suspect it will be passed under urgency because the Government wants it enacted before a petition for a citizens-initiated referendum on asset sales gains momentum.
Committee chairman Todd McClay says there hasn't been any abuse of parliamentary process and he isn't surprised by opposition complaints because Labour and the Greens have always opposed the bill.
When the bill is passed the Government will be able to sell 49 per cent of the shares in four state-owned energy companies - Mighty River Power, Meridian Energy, Genesis Energy and Solid Energy.
Green Party co-leader Russel Norman says Government MPs on the committee used their majority to push the bill through.
"We never really had a proper chance to consider it," he told NZ Newswire on Friday.
"There are still a whole bunch of issues Treasury were never able to provide advice on because they didn't have time."
Hundreds of submitters attended hearings on the bill and nearly all of them opposed it.
Dr Norman says National MPs treated them badly.
"I've never before seen submitters asked how they voted, it was incredibly disrespectful," he said.
"Maggie Barry was asking them how they voted in last year's election - they have a right to make a submission whichever way they voted. It was intimidation."
Dr Norman says he expects the bill will come back to Parliament with hardly any changes and the Government will quickly put it through its remaining stages.
