Amber-Lee Cruickshank went missing 25 years ago - and her mother is overwhelmed by the focus on the case, which she hopes will finally bring the answers she has been seeking for so long.
Amber-Lee was last seen at Kingston on October 17, 1992.
She was with her mother, Nicola Cruickshank, stepfather James Gill and baby brother Danny when she vanished.
Since then there has been no clues or evidence to indicate what happened to the 2-and-a-half-year-old.
Nicola Cruickshank was overwhelmed by the response to her daughter's story.
"I think it is great people are sharing the story as they are all from different walks of life," she said.
"And like it has been said before - you never know who could be out there that may hold the answers we are looking for.
"Even if it's just where she is."
The podcast has reached the number one spot on iTunes and had been downloaded by thousands through nzherald.co.nz and iHeart radio. The podcast is complemented by a feature and short documentary.
"That is a huge number of people reached already so surely something has to come out of this," she said.
Detective Sergeant John Kean, who worked with the Herald on the podcast, is the officer in charge of Amber-Lee's case.
"We would just love to go to Nicky and give her the answers that she deserves," he said.
"We certainly can't discount the fact that someone who was already at Kingston on the 17th of October 1992 holds the key to the disappearance of Amber-Lee Cruickshank.
"There must be someone out there that knows, there has to be someone that knows."
