The family had emigrated from South Africa, arriving in New Zealand on August 28.
Dickason admitted killing the girls but denied charges of murder - mounting a defence of insanity or infanticide on the basis she was so mentally unwell at the time she could not be held fully responsible for her actions.
After an intense and exhaustive five-week trial in the High Court at Christchurch earlier this year, a jury found Dickason guilty of three counts of murder.
In December, she will be sentenced to life in prison and Justice Cameron Mander will set a minimum non-parole period.
He will also decide where she spends the start of her sentence - in prison or at the forensic psychiatric facility where she has been held since shortly after the murders.
Dickason’s legal team includes top criminal defence lawyer Kerryn Beaton KC, specialist criminal barrister Anne Toohey and barrister Abbie Hollingworth.
The Herald sought information about Dickason’s legal funding and the Ministry of Justice last week confirmed she had been granted legal aid totalling $709,109.50 as of October 20.
The bill is expected to increase after Dickason is sentenced, and pending any appeal afterwards.
Under the Official Information Act, the ministry confirmed that the total bill for Dickason included:
$153.970 for three psychiatric or psychological reports - the most expensive coming in at $68,000.
$71,062.50 was spent on a forensic psychologist.
$58,700.81 was paid for expert witnesses including “preparation and court time”.
A further $39.945.78 was invoiced for other payments - known as disbursements - for those witnesses.
$6367.50 was spent on a private investigator.
$9480 was spent on an expert in computer forensics.
$3000 was spent on “expert legal opinion”.
Under the OIA, the ministry also revealed Dickason’s legal team had spent a combined 1714.25 hours working on her defence.
Those hours were also invoiced at different rates, depending on the seniority of each lawyer.
Ministry national service delivery manager Tracey Baguley said the figures provided were based on invoices received to October 20.
Any billing for ongoing work related to Dickason’s sentencing and further legal actions was yet to be considered.
Dickason called three experts to support her defence of insanity or infanticide including Dr Susan Hatters-Friedman, a world-renowned forensic and reproductive psychiatrist who travelled to Christchurch from the US to attend the trial.
Her husband Graham - an orthopaedic surgeon who returned home from a work function to find the children dead in their beds - was working at Timaru Hospital.
His position was the reason the family moved to New Zealand, as part of an attempt for a better and safer life than in South Africa.
“Legal aid is government funding to pay for legal help for people who cannot afford a lawyer,” Ministry of Justice national service delivery general manager Tracey Baguley said.
“Legal aid is an important part of New Zealand’s justice system.
“It helps people to resolve legal problems that may go to court and makes sure that people are not denied justice because they can’t afford a lawyer.
Offenders may be ordered to pay back all or part of their legal aid grants.
