Police say they are fed up with being attacked by out-of-control party goers.
Christchurch riot police arrested at least 10 people after an out-of-control party of over 200 revelers at Cranford Street over the weekend.
Police Association president Greg O'Connor says what's changed now is social media.
"And also the fact that when police and other authorities do arrive, is the utter contempt for them, and the preparedness for those organising the party to them blame the police for anything that occurs."
The invite went out on Facebook, it's believed it was only sent to around 100 people.
