The murder of the 31-year-old Feilding farmer remains unsolved three months after he was gunned down from point-blank range at the end of his driveway, leaving his family hoping for a breakthrough.
Police are not commenting on what information they have received, only saying they are following up on all of it.
Spokeswoman Kim Perks said it had been a "good response" to the show, which was aired to try to appeal to a wider demographic.
Police continue to seek information on three aspects of the case: three chocolate Labrador puppies stolen from the property, two cars seen driving away between 4.45am and 5am, and an unidentified shotgun used for the murder.
Police have previously fielded many calls about the puppies, from Remuera to Marlborough, but they have not been found.
Police are also contacting about 400 Facebook friends of Mr Guy and his wife, Kylee, for more background information.
Mr Guy was killed early morning on July 8 with several shotgun wounds, though police have not revealed where or how many times he was shot.
He had been leaving his house to work on his farm but got only as far as his driveway.
His wife, who was seven months pregnant when he was killed, has moved away from Feilding and says she is unlikely to go back.
She gave birth to their son, Drover Grahame Scott Guy, last month.
The investigation has also taken police to Invercargill, where Mr Guy attended a farming conference two weeks before his death.
They are talking to conference participants and organisers, but have said this was just a routine inquiry, rather than based on evidence that something happened in Southland.
Police have also looked into fires and burglaries near Mr Guy's property, which was the victim of a suspicious fire in 2008. His new house was vandalised in January 2009.
Police are urging anyone with information to come forward.
