Under Bali law a drug user is seen as a victim, and provided some leniency by the courts.
She was also given credit for admitting her guilt.
Ormsby has been in custody at Kerobokan Prison since she was charged in May, the same jail Australian Schapelle Corby served her time for drug smuggling.
The Sydney-based Kiwi was arrested during a police raid of a holiday villa. Inside they found MDMA and hashish in a drawer.
Ormsby was not charged in relation to the larger quantities of drugs uncovered in the villa, but solely on the hashish joint found in her handbag.
Ormsby had not been staying at the villa, but had been given the key by Australian DJ Marco Mazzucco, who was also on holiday in Bali.
Mr Mazzucco had been given the keys by Sydney musician Azaria Byrne, who had rented the villa for three nights, but left early.
Both have denied knowing about any drugs in the villa.
