Police have received more than 50 tip-offs about missing toddler Amber-Lee Rose Cruickshank since offering up to $100,000 for information about her disappearance.
Earlier in April, police announced it was offering the large monetary reward for information or evidence that lead to the identity and conviction of anyone responsible for the toddler's disappearance.
The two-year-old was last seen on October 17, 1992 at a Cornwall St property in Kingston, on the shores of Lake Wakatipu. Police have never established what happened to her, but believe she may have been the victim of foul play. On May 5 this year, Amber-Lee would be 31 years old.
Since offering the reward, Detective Inspector Stu Harvey says police have received more than 50 calls from people offering information.
"The investigation team is making contact with all of these people and will examine, evaluate and review this information. The offer of a reward will remain in place until October 13 2021," he told Newshub.
The Police Commissioner will determine the amount of reward given and apportion payment if there is more than one claimant. Immunity from prosecution may be considered for any accomplice, who isn't the main offender, who provides information or evidence to police.
At the time of her disappearance, Amber-Lee had been staying with her family at the Kingston address, where a number of people were socialising.
Since she went missing, Det Insp Harvey said police have "gone to great lengths to explore different scenarios and investigation leads without success".
"Her mother and family members have been left to worry and angst about what happened to this very young child for far too long. We want to bring them answers and closure."
The toddler's mother, Nicky, told Newshub earlier this month that the disappearance 29 years ago is still as raw today as it was back then.
"I'm asking you from the bottom of my heart, I'm begging you to please give us the answers we are looking for," she said.
"She deserves to come home. We deserve closure. What more can I say? Have a heart. It must be a hell of a burden to be carrying all these years. Because it's been a hell of a roller coaster ride for me and my family."
Anyone with information is asked to contact Police via 105 and reference Operation Oliver: 921030/2144.
