Tomorrow marks a year since the death of a Nelson mum and police are still trying to figure out what happened to her.
Tracey-Anne Harris' body was found in her Marlowe Street home in Stoke on Thursday, February 11, 2016.
Detective Sergeant Ian Langridge said he believed there will people yet to come forward with information.
"While we are building a detailed picture of the events during the days leading up to her body being discovered, the investigation team believe there are more people in the community who hold vital information about what happened to her.
"We are appealing to them to please come forward."
Langridge said hundreds of hours of investigative work has gone into the case.
"We have spoken with a large number of people up until now and the investigation remains open and ongoing.
"It has been 12 months since her death.
"While Ms Harris' family continue to grieve for Tracey, we want to be able to provide them with closure."
He urged anyone with information about the death to contact police.
"Even if it seems small or insignificant, it could be a vital link to other pieces of information we already have.
"I ask anyone with information that may help us solve this case to speak to me as soon as possible."
Harris' son Jade Harris cut off his home detention bracelet in February last year, blaming the trauma of having his mother "murdered" two weeks earlier.
He was sentenced in the Masterton District Court to seven months' imprisonment after the judge cancelled his home detention sentence.
