Mother's anguish continues as reward to solve Amber-Lee Cruickshank cold case expires

A hefty cash reward offered by police to help solve a cold case expires on Tuesday night.

Two-year-old Amber-Lee Cruickshank vanished without a trace from a property in Kingston near Lake Wakatipu three decades ago.

Sunday marks 29 years since two-year-old Amber-Lee disappeared. 

"Her photo will be there and we'll light a candle, and I will talk to her, whether she's out in the universe somewhere," Amber-Lee's mother Nicola Cruickshank says.

Wednesday marks six months since Police offered a $100,000 reward, hoping to spark fresh leads in the cold case.

"I was really hopeful, hopeful that something would come forward that we would get some answers," Nicola says.

Those hopes are now dashed.

"We're still no further ahead, we're like back to square one again," Nicola says.

The toddler was last seen in October 1992 at a property in Kingston. The family was moving from Southland to the West Coast, stopping for the night.

Police initially suspected she'd drowned in Lake Wakatipu but found nothing during an extensive search of the area. In April last year, they changed their tune.

"The inquiry to date leads us to believe that there's foul play involved in Amber-Lee's disappearance," a spokesperson said.

Today police confirmed they'd received 75 calls since the reward was offered and are working making inquiries. Despite the reward period ending, it may be revisited if a member of the public has information that leads to an arrest.

Nicola is making a fresh plea to the public.

"If the person out there that knows something and they're watching this please, I don't care how you do it, just let me know where she is," Nicola begs.

To put an end to this mother's decades-long nightmare.
