A Whangarei candidate in the Denby Ward by-election has gone to police claiming her campaign is being sabotaged.
Huhana Lyndon says she has had nine billboards destroyed or damaged in less than two weeks, four of them were damaged overnight on Sunday.
The single mother of three says the billboards are worth about $400 dollars each.
While Ms Lydon's billboards are being graffitied or ripped down she says other candidates billboards are being left alone.
"It seems like I'm being targeted and I have no idea why, I'm young female and Maori but I'm not political and I'm not affiliated to any political party but I'm the only one suffering from this level of ongoing vandalism," she says.
Ms Lyndon has laid a complaint with Whangarei police.
The by-election was sparked after councillor Jayne Golightly resigned in September when it was discovered she was not a New Zealand citizen.
Ms Golightly promised to get her citizenship and fight for re-election but she's now being investigated by police for alleged electoral fraud.
The former councillor emigrated from the UK as a baby and maintains she didn't know she was not a citizen despite travelling on a UK passport.
