Police have released images of 15 people they want to identify as part of their investigation into the riot at Parliament Grounds in early March.
Hundreds of antivax and anti-mandate protesters occupied Parliament's lawn for more than three weeks before being forcibly evicted on 2 March after lighting fires on the lawn.
The eviction descended into a riot with protesters tearing up paving stones and using them as projectiles against police officers.
A police spokesperson said since then nine people had been prosecuted and one young person referred to youth aid.
That was in addition to the 250 people arrested between 9 February and 4 March.
Detective Inspector Paul Berry said investigators continued to comb through more than 15 terabytes of photographs and videos to identify anyone involved in violent criminal offending.
But officers needed the public's help in identifying the people in the photos they had released.
"This is an enormous task and while we've made significant progress through our investigations, we now need the public's help," he said.
"If you recognise anyone from these images, please provide information to police by calling Crime Stoppers on 0800 555 111 and reference Op Convoy with the relevant photo number."
