One person has died and two others are seriously injured after a major incident in Blenheim.
Police have launched a homicide probe into the incident on Market Pl, where several people were believed to have been stabbed.
There were unconfirmed reports the violence was gang-related. Emergency services were called to the scene about 2:55am.
"The scenes remain cordoned off and there will be a police presence in the area as we work to understand the circumstances of these incidents and ensure the community's safety," Marlborough area commander Insp Simon Feltham said.
"Anyone who was in the area at the time and may have seen anything that could assist is asked to get in touch."
Feltham said several people are being spoken to in relation to the incident.
A worker at a local cafe told Newshub she never expected anything like this to happen in Blenheim.
"It's kind of scary," she said, adding many in the town were feeling "shaken" after hearing the news.
