In late September, New Zealand police arrested and detained a man in the hours after the Wallabies' 33-13 loss to the All Blacks, only to release him later due to the quirk of the law.
Video has since emerged of the incident, published by NZ outlet Stuff, where a man yells "You f***ing stupid f***ot. I've got diplomatic immunity!" as he is arrested.

The man's identity has not been released, and police are yet to detail the charges they seek to press.
Diplomatic immunity is a right commonly afforded to overseas-based representatives giving them freedom to conduct diplomatic business without being arrested or detained.
Diplomats' families also given the same privilege during overseas postings.
Given the seriousness of the incident, NZ police initiated a request to have immunity stripped from the man so he could face justice.
On Wednesday, a week after the incident was first reported, a spokesperson from NZ's Ministry of Foreign Affairs and Trade (MFAT) confirmed Australia had granted the request.
"The Australian government has provided waivers of immunity, enabling next steps to be taken by police," the spokesperson said.
"The matter is now with NZ Police. MFAT won't be commenting further."
NZ Police and Australia's Department of Foreign Affairs and Trade have been contacted for comment.
