Dunedin's 10th annual J Day took place in the Octagon on Saturday.
More than 300 cannabis enthusiasts gathered to protest the prohibition of marijuana.
Even the Robert Burns statue was involved in the event that's celebrated in more than 400 cities worldwide, by having a joint placed in its hand.
Dunedin made international headlines in 2003 when activists marched to the central police station to plant and smoke cannabis in the foyer, and didn't get arrested.
Sergeant Chris George says that this year no arrests were made. He said this was due to a tactical decision that arresting people would just lead to an increase in publicity for their cause, and he said police had better ways to use their time.
