An elderly man is in hospital with multiple stab wounds after he was attacked in a Whangarei park last evening.

The 69-year-old was walking through Riverside Drive Park when he was attacked by at least one offender.

He's in a stable condition in Whangarei Hospital but so far hasn't been able to give police a description of the attacker.

Police are appealing for the public to get in touch with them if they saw anything suspicious in the area or may have found a knife, dumped nearby.
