Mayor Bob Harvey is urging anyone who may have seen missing two-year-old Aisling Symes to come forward.
The Henderson toddler disappeared from a Longburn Rd address around 5:30pm on Monday.
Police and volunteers from the local community have been searching for her ever since.
Investigators are now looking at the possibility Aisling has been abducted.
Waitakere City Council’s Civil Defence team has been involved in the search.
The council has provided a list of registered dog owners in the area following reports Aisling was seen talking to an Asian woman with a black and grey dog just before her disappearance.
Mayor Harvey says the area in and around Longburn Rd is extremely busy, especially during rush hour.
“This little girl was wandering in that area. Somebody must have seen something,” he says.
“If people have seen anything at all, even if they think it is insignificant, they should contact the police immediately.”
Mayor Harvey says the local community’s response to the disappearance has been “just amazing”.
“It's at times like this that you see the sort of community spirit there is in Waitakere.
“All our thoughts and prayers are with the Symes family at this time. We’ve got to do everything we can to get this little girl home safe.”
