The earlier three packages had arrived at her address without being intercepted and after investigating their records, Customs discovered the facts of the deliveries.
On August 14, August 31 and October 9 un-intercepted packages were delivered with content descriptions ranging from "cloth and contact lens", "sample of baby cloth" and "contact lenses".
The two packages that were intercepted, between October and November, contained a total 124.4 grams of pure methamphetamine, meaning Pham imported an overall amount of 405.4 grams.
At sentencing yesterday the court heard Pham was in the unusual position of getting bail not once but twice, despite being somebody arrested for a serious drug offending.
Her personal circumstances came to the forefront of the case at an earlier court appearance this year when she failed to appear for a hearing.
In explanation her defence lawyer Maria Pecotic said her client had presented in a distressed and suicidal state in her office, and she had since been on the phone to a mental health crisis line.
A warrant for her arrest was issued and it is understood her young children were taken into the services of Oranga Tamariki, formerly Child, Youth and Family.
Yesterday Pham read aloud an apology letter detailing her remorse for failing to appear.
She hadn't found an appropriate caregiver for her young children and panicked, she said.
Judge Geoff Rea said the law as very clear that personal circumstances had little part to play when dealing with such offending.
The amount of methamphetamine imported at the hands of Pham would have tallied "a significant number of victims" if it got into the system in New Zealand, he said.
However, the judge accepted the woman had mental health issues, was not a native English speaker and would have difficulty serving her prison sentence.
Pham's defence lawyer's submission of remorse was an "extremely difficult concept" in light of the fact that she offended on bail, he said.
The maximum penalty for importing methamphetamine is life imprisonment.
