A woman accused of taking two young girls in breach of a parenting order says she drove to Parliament to see Prime Minister Jacinda Ardern.

The police have put out an urgent appeal for help to find the two missing girls, Lily, 10, and Pearl, 8.

Police say the children were taken in breach of a parenting order on Christmas Eve, and the last sighting of them was at 11pm on Monday, January 2, at a South Auckland petrol station.

The Toyota Camry in which they were travelling was seen again on the morning of Tuesday, January 3, in New Plymouth, before a woman wanted in relation to their disappearance was found alone in Wellington that night.

She was arrested about 9.45pm, and has allegedly refused to tell the police where the girls are. The woman is due to appear in the Wellington District Court today at 10am, charged with breaching a parenting order.

The police searched vehicles parked in central Wellington but they believe Pearl and Lily could be anywhere between Auckland and the capital.

Speaking from outside Parliament in Wellington yesterday, the woman said in a social media video that it was her hope to see Prime Minister Jacinda Ardern or at least that she would see her.

”There is an extreme problem that I have and I have tried going to many levels but it’s not working. So it’s my humble petition that I get to see her ... I have driven all this way, it has almost taken me 24 hours and without going into too much detail, please Prime Minister Jacinda Ardern, we need you.”

Detective Senior Sergeant Kevan Verry said the woman has been meeting people through Facebook in the time that the police have been looking for her and the children.

“It is possible she has left Pearl and Lily with one of these people.

“We believe these contacts may have been misled or are unaware of the true circumstances in this case, or the serious concerns that are held for the children’s welfare.”

Police are asking anyone with information to call 111.

They also want to hear about any sightings of a 1994 silver Toyota Camry with the licence plate CLR45.
