It's every parents' worst nightmare and grave fears are mounting for a missing two-year-old girl.
About 100 people have been scouring the area of the west Auckland suburb of Henderson from where Aisling Symes went missing about 5.30pm Monday.
No stone is being left unturned in the search.
A hundred police and search and rescue officers have been combing their way through five streets surrounding the Henderson house where little Aisling disappeared, and the creek behind them.
A child's t-shirt has been found in the creek on Tuesday. Police can't yet confirm the t-shirt belonged to Aisling.
Inspector Gary Davey of Waitakere police says the girl's disappearance is a very serious concern for police. He says police know that Aisling liked the water.
The two-year-old went missing from the front yard of her late maternal grandparents' home.
Her parents were inside cleaning it, ready to sell.
"I think Aisling probably went into that house possibly thinking she would see granny and grandpa and they weren't there so she might have gone off," says Ailywn Symes, grandmother.
Her family say she was a typical curious two-year-old.
Dozens of neighbours and locals have joined in the hunt.
It's just sad that there is a little kid out by herself. I've got a three-year-old little brother and he's gone missing before," says a young local.
Aisling's parents, older sister and relatives spent Tuesday at the home she disappeared from praying for her return.
"Our best hope at this stage is that somebody's rescued her and for some reason hasn't come forward," says Aithne Potts, Aisling's aunty.
Police are still waiting to hear from an Asian woman in her mid-thirties seen approaching the toddler shortly before she disappeared.
"She was seen walking up behind her, touching her on the shoulder and walking around the corner. Our hope is that she was trying to help her," says Davey.
Meanwhile, the search continues and police from Whangarei and Hamilton are on stand-by to help if it continues on Wednesday.
But as another cold night fell, everyone was hoping for good news before then.
