Tensions over the occupation of Parliament flared briefly on Saturday evening as police wearing riot shields and helmets faced off against a group of protesters and a number of cars drove up.
The resurgent activity, which took place on the 19th day of the protest, appeared to catch police off guard.
An officer said he was unaware other protesters were about to arrive.
Several cars, some of which are towing caravans, appeared to arrive at the protest site around 9 p.m., to cheers from the crowd.

Further police reinforcements arrived on Bowen St around 9.10pm.
A protester shouted at the police ‘what are you going to do when all the tractors come?’
Another larger crowd gathered at Bunny St opposite the station, near Aitken St.
The group of several hundred protesters were cheering every minute or so when a new car of protesters carrying flags arrived from Thorndon Quay.
New reinforcements of protesters continued to arrive in a steady stream as midnight approached. By then, tensions had eased considerably and a Thing reporter at the scene said there were no more police with riot shields.
Crowds continued to cheer late Saturday night as cars carrying protesters arrived sporadically.
Earlier, officers were seen moving an escorted forklift down Featherston Street. It was used to move a concrete block near the Thistle Inn on Mulgrave Street.
The forklift returned to base, escorted by police, around 10:30 p.m.
