Police were called to a fight between a group of hoki fishermen and two men at Waitohi Wharf, in Picton, just after midnight yesterday.
When police arrived, they saw one man had a severe cut to his hand.
None of the men were willing to talk about what had happened, but police watched security footage, which showed one man chasing three men with a large knife.
A 17-year-old male fisherman was later arrested for possession of a knife in a public place and injuring with the intent to cause grievous bodily harm. He was due to appear in Blenheim District Court today.
