The investigation into the disappearance of two-year-old Aisling Symes in Auckland is to be further boosted by additional police staff.
Already about 60 police are engaged in trying to locate Aisling, who went missing about 5.15pm last Monday outside her deceased grandparents' home in Henderson.
Inquiry head Inspector Gary Davey said today those numbers would be increased again today and tomorrow.
He said police were continuing with an area canvas today and were still searching for a breakthrough in the case.
They were working through a list of persons of interest and through reports of suspicious activity, from information supplied by members of the public.
Video shots of Aisling dancing were released yesterday to help to keep the case in the minds of the public.
Aisling was with her parents and her five-year-old sister, when she went missing outside the house, which was being tidied up in preparation for sale.
Her mother, Angela, told of how she had been checking a washing machine just before she realised Aisling had vanished.
The last confirmed sighting of the girl was with an Asian woman walking a dog in Longburn Rd.
The case has aroused international interest, with Irish media following developments, as Aisling's father hails from County Waterford.
In England, the parents of missing British girl Madeleine McCann expressed their sympathy with the Symes family.
Madeleine disappeared on holiday in Portugal in May 2007, just days short of her fourth birthday, while her parent dined at a nearby hotel.
Despite a massive worldwide hunt, she has not been found.
Mr and Mrs McCann said their thoughts and prayers were with Aisling and her family.
"We wish Aisling's parents the strength and support they will be needing at this most painful time, and we join them in hoping for Aisling's safe and speedy return," they said in a statement.
"We urge anyone who has any information about Aisling to come forward to the local police as soon as possible and end this family's suffering."
