Greens co-leader Russel Norman has been forced into an embarrassing admission – that party activists are behind widespread vandalism of National Party election billboards.
Mr Norman told reporters that Greens members had recognised the voice of the self-confessed vandal when he spoke on the radio this morning.
He is Jolyon White, the partner of Mr Norman’s executive assistant.
"I believe the defacing of the billboards is vandalism and condemn these actions," Mr Norman is reported as telling media at Parliament.
"I am incredibly disappointed about what they have done."
Stickers were posted on about 700 National Party billboards on Sunday night reading "the rich deserve more" and "drill it, mine it, sell it".
Mr Norman told reporters he had apologised to the PM and had informed the Electoral Commission.
