Hundreds of motorcyclists have descended on the streets of Wellington for anti-lockdown protests on Tuesday.
Footage shows hundreds of bikies arriving at the gathering near Parliament, where people are protesting against COVID-19 vaccine mandates and lockdown restrictions.
A social media post by one motorcyclist said they were "uniting here in Wellington" and "making thunder".
In a statement, police said officers were monitoring the gathering at Parliament on Tuesday.
"Police, together with our civic and community partners, will respond to any issues as they arise," a spokesperson said.
"Police have the ability to take enforcement action against anyone in breach of alert level restrictions - this could include an infringement notice or a court summons."
Wellington is currently at alert level 2, meaning gatherings of no more than 100 are permitted.
