The Green Party says the National Party's plan to use money from partial asset sales to upgrade schools is just to appease opponents of its policy.
Last week National's leader John Key announced $1 billion in proceeds from partial sales would be ring-fenced for education projects.
The Green Party's education spokesperson, Catherine Delahunty, says it's ludicrous to partially sell off state owned assets to fund schools.
She says it's simply appeasement to people who don't want the assets to be sold.
But National's Anne Tolley says the $1 billion will go towards work on schools including repairing leaky buildings, earthquake resistance and modernising.
The Labour Party says it would take a sustainable approach to education funding, which isn't a one-off fire sale of assets.
The Maori Party says it wants to see money invested in a long-term education strategy which supports children right up to employment.
