Police are continuing their search for two children who left a Tuakau address overnight on Monday.
Inspector Kay Lane says police do not hold specific concerns for the safety of Te Morehu McLean (15) and his sister Anahera (7), and they are making further enquiries with their extended family in Auckland to help locate the children.
The pair left their caregiver's residence late Monday night. Police have been searching the wider area and have spoken to neighbouring property owners. A helicopter has also been used in the search.
"We do not believe there are any suspicious circumstances involved, however we would really like to hear from anyone who knows their whereabouts, so we can confirm they are safe," said Inspector Lane.
"We believe they may be heading north towards Auckland where they have extended family and would like to hear from anyone who has information about their whereabouts that may help us find them."
Because of their young ages, Insp Lane said she didn't want to divulge why they were in the caregiver's care.
She said the pair had a "strong relationship".
"Our concern is that she's seven, being a very young age, but realistically she's with her older brother and he's very protective of her."
Insp Lane said it didn't appear there was any kind of dispute before they left the house, and it appeared like they'd "left of their own volition".
Te Morehu is described as Maori, 5 foot 7 inches tall, and of solid build and with short dark hair.
He was last seen wearing Nike shoes, light brown coloured pants and a Kathmandu puffer jacket.
Anahera is described as Maori, of average height and small build. She was last seen wearing a "Frozen" branded onesie.
People can provide information to Counties Manukau Police on 09 261 1300 or contact 111 if they see the pair.
