Sister's plea: We hope you can give us a ring

A missing Kerikeri woman's partner believes she was abducted because she would never leave her four-year-old son on his own.
Cristel De Vetten, 30, disappeared from the Matua Block home she shared with boyfriend John Craven and son Jaxon last Friday, leaving Jaxon by himself.
She was reportedly withdrawn and depressed in the weeks leading up to her disappearance. Work and Income staff, Jaxon and Mr Craven were the last people to see her.
Northland police Detective Senior Sergeant Mike Pannett said foul play was a "real consideration" but would not be drawn on the possibility she had been abducted. He believed Ms De Vetten, a childcare worker, could still be alive.
It was revealed yesterday that Ms De Vetten was depressed and had had a stressful year because of a custody battle with a former partner over Jaxon.
Mr Craven said the past week had been hard as he could not understand why his partner, who had lived with him since late last year, had disappeared. She had left the bush-surrounded house with light clothing and left her handbag and car behind.
He said the pair had had a "kiss and a cuddle" before he went across the road to spray gorse last Friday morning.
The pair had met with Work and Income staff that day because Mr Craven wanted Ms De Vetten to get some financial help.
When Mr Craven, a builder whose family owns land at Matua Block, returned later, Jaxon was sitting on a couch with a chick he had accidentally killed. Mr Craven called out for Ms De Vetten but she could not be found.
She was reported missing on Friday afternoon.
Ms De Vetten's depression was revealed at an emotional press conference attended by Ms De Vetten's sister Nicki and friend Carmen outside the Kerikeri Police Station yesterday. The women did not want to give their last names.
Nicki said her sister had had a "trying time" over the custody battle. "Cristel, we love you and we miss you and we hope you can give us a ring," Nicki pleaded.
Jaxon is being looked after by family in Kerikeri. Nicki said he had not been told anything was amiss with his mother.
Carmen said she had last seen her friend of eight years two weeks ago, and that she did not seem out of character.
Ms De Vetten had lived in the Netherlands and New Zealand, mainly in the Far North, as a child.
Her mother is deceased and her father lives in Australia.
She had been working at early childcare centres around Kerikeri and loved children. Nicki said her sister was caring, honest, gentle and a "good mum".
Police said people who had been in contact with Ms De Vetten recently had said she had been "increasingly withdrawn" in her behaviour.
"There's certainly an aspect of depression we're looking at," Mr Pannett said. Mr Pannett did not think the visit from Work and Income had upset Ms De Vetten.
Police, forensic scientists and a corpse-seeking dog have scoured the area around the couple's modest Matua Block home since last weekend.
However, no sign of Ms De Vetten, her clothing or possessions has been found. No sign of struggle was noted by police.
An aerial and marine search near Ms De Vetten's home will continue this weekend.
