A $100,000 reward and immunity from prosecution is being offered by police for information about the disappearance or death of Southland toddler Amber-Lee Cruickshank.
Her family say it is their last hope of finding out what happened to the little girl - who vanished without a trace almost 29 years ago.
The Herald can reveal that the reward will remain in place for six months from today.
Amber-Lee was last seen on October 17 1992 at Kingston, a small town at the southern end of Lake Wakatipu.
The toddler was there with her mother, stepfather and baby brother - the family had left their home in Invercargill and were heading to the West Coast to start a new life together.
They stopped at Kingston for a night to catch up with friends.
After an afternoon by the lake and a barbecue, the toddler vanished and despite exhaustive land and water searches there has been no sign of her in almost three decades.
Police met with Amber-Lee's family - who now live in the Christchurch area - late last year and a reward was discussed.
After working through the approval process at Police National Headquarters the reward was confirmed last week and announced publicly today.
Police will pay up to $100,000 for material information or evidence which leads to the identity and conviction of any person or people responsible for Amber-Lee's disappearance.
And they will consider immunity from prosecution for any "accomplice" who provides information or evidence to police as long as they are not the "main offender".
Detective Inspector Stu Harvey said after 29 years police hoped someone would finally come forward and help them solve the mystery.
"While we don't know where she is or what happened, we believe she may have been the victim of foul play," Harvey told the Herald.
"There is someone out there who holds the key to the truth."
Harvey said over the years police had conducted a significant number of inquiries into Amber-Lee's disappearance.
"We 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."
Amber-Lee's mother and brothers spoke to the Herald about the reward offer.
"Twenty-nine years of not knowing what happened to our beloved Amber-Lee has been 29 years of pain, anger, frustration and torment - with endless searching and praying for this nightmare to end," said Nicola Cruickshank.
"To have answers, to have closure, to have Amber-Lee come home - that's all we want.
"And now we are living in hope, praying that this reward will enough to entice whoever holds the key to the truth of Amber-Lee's disappearance and her whereabouts to come forward - whether she has passed, or is alive."
Nicola Cruickshank said she had never given up hope her daughter - who would have turned 31 on May 5 - would be found.
"We have done everything possible and within our power to find the answers.
"I feel this reward is our last resort."
She appealed to anyone with any information to speak up.
"We are begging you to come forward and do the right thing," she implored.
"Put an end to this nightmare and bring Amber-Lee home - where she belongs.
"She deserves that much at least."
Harley Cruickshank was just 5 when his sister vanished. He was staying with friends of the family while his mother and stepfather relocated and was to join them once they had unpacked and settled in.
He said there had been a "constant void" in his life but he tried to have hope that she would be found.
"Having to relive it every day, every birthday, every Christmas or memorial - it takes its toll on us," he said.
"I can't imagine the pain my mum goes through."
Like his mother Harley vowed never to give up on Amber-Lee.
"All I can say now is please, if anyone knows anything, speak up - change our lives, and your own," he urged.
"This must be a burden to carry."
Harley said the reward was not about speculating what happened or people passing opinions or judgment on the case.
"The focus here is to bring her home - not how it happened or what happened."
Danny Cruickshank also spoke about his missing sister, saying it had been "hard" growing up without her, and living in the shadow of the mystery.
"To watch mum going through all the heartache and not being able to do anything… has been hard," he said.
"Now that I've grown up and got a daughter of my own I can't even bear to imagine how hard and painful it truly is.
"Our sister did nothing to deserve this and yet she was the one to suffer.
"If anyone knows anything - speak up. You owe whoever is responsible for this nothing."
In 2017, to mark the 25th anniversary of Amber-Lee going missing, the Herald worked with her mother and police on Chasing Ghosts - a six-part podcast series, news feature and mini-documentary about the case.
Chasing Ghosts was researched and written by senior crime reporter Anna Leask.
Visual journalist Mike Scott did the field recording and produced the mini-documentary.
You can listen to the series by clicking on the embedded audio file above or via iHeart Radio, Apple Podcasts and your usual apps.
In producing the series, Leask had unprecedented access to Amber-Lee's family and others closely connected to the case, including both police officers who have led the investigation.
They also spoke, for the first time, the people considered of interest to police.
Chasing Ghosts tells Amber-Lee's story in unflinching and enormous detail - and for the first time in full.
Leask said the project aimed to bring fresh attention to the case in the hope that someone comes forward with information that could help bring Amber-Lee home.
The last major reward offered by police was in May 2019 for information leading to the arrest of the person or people who murdered Christchurch mum Angela Blackmoore in her own home while her toddler was sleeping nearby.
Blackmoore was 10 weeks pregnant when she was killed - stabbed 39 times in her kitchen - in August 1995.
Less than six months after the reward was announced, three people were arrested and charged in relation to her murder.
Last year Jeremy Powell, 45, was jailed for life after pleading guilty to a charge of murder.
Two other accused remain before the courts.
