Just as spring follows winter, so too do parodies follow election ads. There's been plenty of billboard 'art' (some of it quite funny). There's been a song about John Key (that's been banned from being broadcast by the Electoral Commission). And there's been a satirical Colin Craig website (that can't be shut down because it's outside New Zealand jurisdiction). And now YouTube user Gabriel Page has tweaked National's first campaign TVC to show a slightly different type of rowing.
And as for the comparisons between the track used in the ad and Eminem's Lose Yourself, make your own mind up.
