Ten people have been arrested in relation to a fatal stabbing in Blenheim this morning.
Police say the altercation, which happened in Market Street about 3.30am, appears to have been between local Recognised Seasonal Employer workers and members of the Rebels gang from outside Marlborough.
A man died at the scene and two people are in hospital in a serious condition.
Marlborough Area Commander Inspector Simon Feltham said those arrested faced a range of charges, including murder, wounding with intent, asssault and disorderly behaviour.
"We acknowledge that today's incident will be concerning to the wider community," he said, adding the further arrests were likely.
The first will appear in the Blenheim District Court tomorrow.
Cordons in the area have been removed but police will continue to have an active presence in the area as their investigation continues.
