Nine anti-drilling protesters have been sighted on paddle boards in Wellington Harbour near the seismic survey vessel Duke off Aotea Quay this afternoon.
Senior-Sergeant Marc Clausen from police communications said the police launch Lady Elizabeth IV had been sent to clear the area.
The Duke was due to sail from Wellington this afternoon.
Interislander freight-only ferry Arahura's berthing at the ferry terminal was delayed while the situation was resolved.
