More than a dozen people have come forward with information after a new police appeal for help finding the killer of Feilding farmer Scott Guy.
Mr Guy, 31, was found shot dead on the driveway of his home in Aorangi Road in July last year.
Police on Tuesday released photos of obscene graffiti and damage done to the Guy family's partially built home on the property in January 2009.
They say calls have been made to police and the Crimestoppers line and the investigation team is now following up on the information.
Police are urging anyone else who knows anything about the vandalism, or Mr Guy's death, to contact them.
Mr Guy's sister Nikki Guy says she believes it is just a matter of time before her brother's killer is found.
She told Morning Report the police are just as determined as the family to find her brother's killer.
