The police investigate after an elderly man has been attacked in his home in Greymouth.
The man responded to a knock on his door and was attacked by an unknown man around Sunday at 20:15.
The intruder entered the house with at least one employee and took several items before departure.
The incident was a "cowardly attack" on a vulnerable member of the community, said acting detective senior sergeant Kirsten Norton.
The man was the only person at that time at home and suffered some injuries but was not admitted to the hospital.
A scene review is performed.
Police would like to hear someone who may have seen something in the Marsden Road block from Shakespeare Street to Palmerston Street on Sunday night or someone who may have noticed suspicious activity around his homes.
Members of the public with information are encouraged to contact the Greymouth police on 03 768 1600 or Crimestoppers on 0800 555 111.
