National Party deputy leader Nicola Willis has been forced to remove one side of her two-sided political billboards following a change in Wellington City Council guidance.
Willis is National's candidate for Ōhāriu and her campaign team was initially advised by Wellington City Council that political parties could have double-sided signs.
A National Party spokesperson said the Council then updated its guidance "saying this was not permitted for full-size signs".
A Wellington City Council spokesperson said as with most election campaigns, the council receives complaints about billboards and their size and location.
"When we receive a complaint we investigate and take action as necessary," they said.
"In this instance, the complaint relates to the size and number of hoardings. We have been in touch with the National Party and the situation is being addressed."
The National Party spokesperson said campaign volunteers have responded to the updated guidance by removing one side of its signs.
"Our campaign will continue to act on council advice."
Newshub first came across Willis' billboard battles when Labour MP Grant Robertson bought it up during question time in the House on Tuesday.
During questions from Willis to Robertson, he said he'd "be happy" in assisting Willis in taking down the billboards which break the rules.
"Is that all you've got?! Willis replied.
It comes after political parties across the floor and their hoardings were targeted by vandals at the weekend.
National Party leader Christopher Luxon urged vandals on Monday to "give it up, there are more important things".
"[If] you feel strongly about something, get involved, get off the sidelines, enter the arena, stand as a candidate yourself if you want to change something."
