National’s campaign manager at the time Steven Joyce described the use of the “Eminem Esque” track as “pretty legal”.
On Wednesday, National leader Christopher Luxon told Newshub he was not aware of any further copyright issues.
Deputy leader Nicola Willis told reporters today she expected copyright law was followed and directed any further questions to party staff.
The Herald has contacted the party for comment.
Late last year, National had to remove an Instagram video attacking Labour because it had used a Katy Perry song “out of context” in the video.
Perry’s Did Somebody Say tune was attached to a video published on the social media app by National, which was titled Just be rich ft. The Labour Party - a reference to the Just Eat food delivery company, for which the song was an advertisement.
The video showed the percentage increase in the cost of various food items with the caption “Under Labour, food prices have skyrocketed”.
However, the move backfired after Just Eat-owned Menulog, which operates in New Zealand, contacted National and requested the video be removed over an apparent copyright issue.
In April, National was forced to re-edit a campaign ad to avoid breaching copyright laws after a trailer had to be taken down for potential copyright infringement.
National uploaded a trailer for a video on former Minister Stuart Nash’s Cabinet Manual breaches, which used extensive footage from Newshub’s TV bulletins. Warner Bros Discovery, the owners of Newshub, sent a “cease and desist” cautionary letter asking National to take the trailer down.
