It's Nelson versus Christchurch for the title of New Zealand's official home of rugby.
According to the Nelson Rugby Football Club, the game was first played there in 1870.
However, Christchurch Football Club is claiming rugby was first played there seven years earlier.
Although at the time it was not called rugby, there is a painting of a re-enactment game in the club showing Christ's College playing the gentlemen of Christchurch in 1863.
With Christchurch saying "without a doubt" the first game of rugby was held there and Nelson saying it's "fake news", Seven Sharp reporter Julian Lee tried to separate the fact from the fiction in the video above.
