Police have recovered a body from the water after a vehicle went into the Ruahini Canal near McLaren Falls Road in Omanawa earlier today.
1 NEWS understands the truck had lost control on a corner and ploughed through two fences.
Police say the canal water levels were lowered to give them better access to the area.
A local in the area said the canal is about four metres deep where the truck had driven in.
Police were alerted to the incident around 1:20pm and inquiries into the incident are ongoing.
A formal identification process is underway.
