Justice Graham Lang said the trio were arrested after police intercepted a busy network of drug dealing.
Rotorua man Graeme Williams, who earlier this year was jailed for 10 years and 10 months for his part in the opeation, was a "busy street dealer" at the "top of the table", Justice Lang said.
McLaine was a "trusted lieutenant" who transported cash and drugs for Williams. He used his own contacts to source methamphetamine and accepted that 266g of methamphetamine had passed through his hands.
Justice Lang said McLaine had not made any commercial gain from getting the methamphetamine but obtained the drug to feed his habit.
He said Haira committed the offences while on bail for similar offending and was already serving a two-and-a-half year jail term. Haira and Phillips had pooled their funds to buy more of the drug at a cheaper price.
Justice Lang said Haira had 26.7g of methamphetamine for supply and described her as a "busy retailer" of the drug.
She had a large amount of support, had made considerable progress while in jail and had many good qualities but needed to ensure that she stayed well clear of drugs in the future, Justice Lang said.
