Details of a funeral for the young victims are yet to be made public.
Last week Graham Dickason, who moved his family to Timaru to take up a role at the hospital as an orthopaedic surgeon, said he had forgiven his wife.
"I honestly believe she is a victim in this as well," he said in a deeply moving letter he penned to be read at a vigil to mark a week since the alleged murders.
"I have already forgiven her and I urge you in your own time to do the same ... it is the key to healing this loss we have all experienced."

Lauren Dickason's brother today provided images of a service held in Pretoria in memory of Liané, Maya and Karla.
Graham Fawkes did not want to speak in-depth about what had happened to his nieces but shared photos taken at a "celebration" of the girls earlier in the day.
"We love them and we will always love them," Fawkes told the Herald.
He said the gathering was held in Pretoria at a public space.
It was "more for family and close friends" but some members of the public also attended.
Three photos of the girls were lined up in a grassy area near a small pond.
The photos bore the children's names and a description of each of them.

"A beautiful little girl inside and out. You were such a chatterbox with an infectious laugh," Liané's read.
"You loved cuddles, you enjoyed baking - even though you ate a lot of the mixture before it was baked.
"You were so creative and loved your stickers and sparkles.
"You were kind and always cared deeply for those around you.
Karla was born with a cleft lip and her grandparents said last week she did not have the best start in life - but she overcame that and was brave and an explorer.
At today's service she was described as "a beautiful little girl who was feisty, independent and strong".
"Yet, kind and caring," her photo caption read.
"You loved a cuddle and loved early mornings.
"Your smile left an impact on each person that met you.
"You were such a cheerful and happy little soul, your little personality was contagious."

Maya was remembered as "a beautiful gentle little girl who was always smiling".
"And a real little charmer who knew just what look to give us to get one more sweetie.
"Playful to the core, so happy and cheerful - you loved tea parties and perfected the pinkie finger ."
