The Greens have issued a 14-point asset sales "blunder list" as opposition parties increase pressure on the Government to scrap its partial privatisation programme.
Monday's decision to delay the Mighty River Power share sale until March next year has given opponents new opportunities to claim the sales programme is off the rails.
Green Party co-leader Russel Norman says there has been a series of mismanaged crises.
"The asset sales programme has lurched from blunder to blunder while National has neglected the economy and failed to create jobs," he said on Thursday.
The party's "blunder list" is a collection of Government statements explaining why it needs to partially privatise four state-owned energy companies, statements the Greens say have been "comprehensively disproved".
Labour leader David Shearer says Prime Minister John Key's credibility is riding on selling 49 percent of the shares in the companies and raising between $5 billion and $7 billion.
"The uncertainty around the asset sales is increasing the risk that they will be sold at rock bottom prices," he said.
"What is the Government going to do now, borrow more money?"
Ministers are heading into five weeks of discussions with iwi over water rights after announcing the Mighty River Power share float won't go ahead in November, as originally planned.
Mr Key says he wants "clarity and certainty" around Maori claims that their rights will be compromised.
The Maori Council, which sought the delay, has welcomed it but says it is keeping its legal options open.
It would have sought a High Court injunction if the government had insisted on the November deadline.
The Maori King is calling on all Maori across New Zealand to join forces to protect what he says are their rights and interests.
King Tuheitia is to hold a hui at Turangawaewae marae next week to discuss the Government's response to the Waitangi Tribunal report on water rights.
"The king is being very clear – this is the most important issue to face Maori," says Kingitanga spokesman Tuku Morgan.
"The invitation is open to all our people who want to talk in a constructive way about protecting the rights and interests of our people."
The hui will also address the consequences of the proposed sale of state-owned assets.
