South Island toddler Amber-Lee Cruickshank disappeared 25 years ago from a small town on the shore of Lake Wakatipu.
Despite exhaustive and repeated searches, there has never been any sign of the little girl.
The Herald senior crime and justice reporter Anna Leask investigated the famous cold case in a bid to generate some answers for the toddler's family.
In October, to mark the 25th anniversary of Amber-Lee, the Herald released Chasing Ghosts, a six-part podcast series, news feature and mini-documentary about the case - one of the most well known mysteries in New Zealand history.
NICOLA CRUICKSHANK: It took 10 days to give her her name.
I used to sit there and I wrote down on a pad all these names and then I eliminated them with things that didn't ring right or true and then I came up with Amber-Lee Rose Cruickshank which I thought had a lovely ring to it.
The rose was because she was like a little rosebud.
From the day she was born she always had red cheeks and the older she got they continued to stay red and I don't what that was about...
Nicola Cruickshank will never forget the details of her daughter Amber-Lee's birth.
May 5 1990.
2.45pm.
7 pound and nine ounces.
Bright blue eyes, fine fair hair and those rosy red cheeks.
NICOLA CRUICKSHANK: I remember watching her coming into the world and I was awestruck to see that she was a little girl.
NICOLA CRUICKSHANK: Yeah, no, that was it, that was the turning point for me.
I'm Anna Leask, crime reporter for the New Zealand Herald.
In this episode of Chasing Ghosts we look at Amber-Lee Cruickshank's short life - and her mother's descent into drugs and gangs.
For years people have speculated that Nicola's lifestyle was linked to her daughter's disappearance – that Amber-Lee was snatched or sold because of a drug debt or for some kind of payback or vendetta.
In episode two we heard police say that simply isn't true.
NICOLA CRUICKSHANK: She was bubbly, a real chatterbox, loved to help, whether it was in the kitchen, hanging out washing or throwing the pegs everywhere so you had to go and pick them up before you could hang the washing.
Yeah she was joy to be around, she was always happy, she always had rosy red cheeks, she was always smiling.
She doted on her big brother, followed him around like a bad smell which was quite annoying sometimes for the big bro but I don't think he would mind if she was to ever do that again.
Nicola's close friend Katrina Atariki moved in with the couple and had a lot to do with the kids.
Atariki still carries a photograph of Amber-Lee around in her handbag.
It's worn around the edges and you can tell it's been handled often over the years.
Got beaten to a pulp in a nightclub one night by one of the women and put on the back of a bike and taken to Christchurch and dropped off at, what I didn't know then but I soon found out, was a working house - a brothel.
One of the guys I went out with held a gun to my head and was going to kill me and when he was jumped by a girlfriend a lot older than me I managed to escape and became involved with this gang because of it.
Yeah, so, at the ripe old age of 16, I soon learned how to earn my keep.
That happened until I met Harley's dad and fell pregnant with him.
It was a fling relationship I suppose you'd call it, he had a mrs which was unbeknown to me until a few years later.
At 18 Nicola gave birth to her first child, a son she named Harley.
I totally lost the plot, I was not, um, coherent, probably for three years of my life - because of the drugs.
I did a lot of morphine intravenously, really wasted.
I ended up on the methadone programme.
And then I don't know what made me snap, I can't remember, it could have been an article I did after three years or something, I don't know what it was but I decided to turn my life around - again.
There's many times I've tried and tried to get my s** together, and failed.
I got a week's worth of takeaways of methadone, I sold five of them and took two with me and went on a road trip down south with a lot of weed and took myself off the 'done and sort of got straight.
I spoke to James a few times this year and he was always reluctant to speak publicly about the case.
He didn't want anyone, in his words, "cashing in" on Amber-Lee.
When I explained to him that I was working with Nicola, and that our aim was to try and get answers, he agreed to be interviewed.
But when the time came, he pulled out and then cut off all contact with me.
I know James has struggled with the loss of Amber-Lee over the years, he told me he's dealt with a lot of s*** since she went missing.
So maybe reliving it all was simply too hard for him.
She met a new man, who she married, and had another baby - Jacob.
Nicola was finally stable, pretty much drug free and happy.
Until her marriage fell apart.
NICOLA CRUICKSHANK: I kind of hit another rocky patch, failed again you know, there was nothing good in my life, it turned to custard and I got involved in methamphetamine.
And then I ended up heavily involved in the meth scene.
In 2007, drug-addled and desperate, Nicola put her faith in Sensing Murder, the TV show that features so-called psychic detectives seeking answers in cold cases.
Nicola says the experience sent her into another spiral - the worst one yet.
NICOLA CRUICKSHANK: It was one of the hardest interviews I've ever had because for 15 years I believed that there was every chance that Amber-Lee was still alive you know, that she was still here.
And then to be told on national television that she's been strangled or had her neck broken and that I know who did it - wow.
You have no idea what that did to me inside and how hard it was for me to keep that together.
I went f*** the world, I just can't take this anymore.
I hit the meth pretty hard and started making it and in turn got set up and turned over and ended up in jail.
NICOLA CRUICKSHANK: That was one of the hardest things I've ever had to do.
For the first time in, crikey, I was 40, so in 20 odd years, had I been clean and I had to learn how to live life without drugs.
And part of that was learning how to deal with the emotions that you felt when things like this arose or other loved ones that were very dear to you have passed on and I'm just grateful to the judge that he gave me jailed because those tools that I learned helped me in these last 10 years to survive how other people survive.
And I feel the emotions now, and they hurt - they hurt like f*ck.
They're raw but I have other ways and means of dealing with it now.
And through support, I have more support now than I did back then.
I mean, you've gotta understand, junkies are not very nice people, I mean, I wasn't a very nice person for a very long time.
Nicola now says prison was the best thing that ever happened to her.
NICOLA CRUICKSHANK: It was the first time since I could recall ever having structure, um, a roof over my head, three meals a day, routine, and the best thing of all - drug free for I can't even count up the years
Some say 'you're a junkie and junkies never change' but that's bull**** because you can if you want to.
Apart from cannabis - which Nicola has always been open about using - she is now drug-free.
It's been almost 10 years since she was sent to prison and finally got clean.
I've held down a job and run my own business and still got a job for the last five-and-a-half of those years.
My boys are my life, they really are.
I live for them.
If it wasn't for my sons, I wouldn't be here.
I live for my sons and now my grandsons, they're my world, they rock.
In spite of her dreams of getting clean on the day Amber-Lee disappeared, as we've heard, Nicola was trying to get high when her daughter went missing.
That fact cannot ever be hidden, and Nicola accepts that.
And yes, I did choose to bleed those poppies that night but I didn't choose for someone to come along and do what they did to Amber.
And yes, it was the wrong choice, but that was my life back then - it's totally different to who I am now.
I carry a lot of guilt because of that, I always will... people tell me 'you shouldn't feel guilty Nicky'.
But I do, because she was my responsibility, she was my daughter, I should have been taking care of her instead of worrying about taking care of others - because basically that's what I was doing.
You know, I should have put my foot down and said no, and dealt with the kids, but I didn't - and that was the wrong choice, and now I'm paying the price.
I don't wish this upon my worst enemy - even the bastard who's done this.
I don't wish it upon them, to have to live through this and carry the guilt that you weren't protecting your child at the time - you were looking after yourself and others.
It's easy to judge Nicola, but I really want people to look at the bigger picture before writing her off.
The fact is, she could have been doing anything at the moment Amber-Lee disappeared and the outcome would have been the same.
She could have been in the shower, she could have been doing the dishes - anything.
It comes down to this - regardless of what she was doing she thought the little girl was with James when she vanished.
I want people to understand - or try to - what it must be like to have a beautiful little girl taken away, suddenly and with no warning, to spend 25 agonising years wondering, searching, asking, and getting no answers.
NICOLA CRUIKSHANK: Unless this has happened to you and you have gone through this yourself, you've got no idea, no idea what this does to you, how it makes you feel, how it makes you think, how it makes you act, what you do to numb it - or to deal with it.
It's just the answers, you know? Is she dead ? Is she alive?
I've been thinking about this, I feel like I'm back at scratch, I'm back at the beginning.
I am no further ahead 25 years down the track than I was the day she went missing. Because I'm still asking that same question - who did this? Where is she?
This is the reason why I do these interviews - to put it out there, to voice it, to be heard, you know?
Amber-Lee deserves that, she deserves to be in people's eye, you know, in their minds, have people thinking
I'm her voice - and I'm not going to stop looking not until the day I get some answers or she comes home.
