Two Kiwi artists are pushing back at the Electoral Commission, saying they are producing art and not political advertising.
Otis Frizzell and Mike Weston have been selling posters that show Jacinda Ardern and the word "aroha", the Maori word for love.
Some of the posters have been put up around the country, but the electoral commission is now investigating whether the posters are breaching the rules about political advertising.
Otis Frizzell is one of New Zealand's best known graffiti artists. He joined Andrew Dickens to explain his thinking behind the poster.
