New Zealand First leader Winston Peters - eyeing a political comeback - says taxpayer money is being used for an all-out assault on western values.
In a speech in Auckland, he warned of a powerful elite, devoted to the destruction of "our cultural inheritance".
He promised his party, if re-elected, would take action, such as changing every government department's Te Reo Māori name back to English.
New Zealand First was ejected from Parliament at the last election, falling short of the 5 percent threshold required for parties with no electorate seats.
The party has been sitting around the 3 percent mark in recent polls.
Peters spoke to Māni Dunlop.
