A woman blackmailed a man she described as her "sugar daddy" out of $7700 while so addicted to methamphetamine that traces of the drug were found in a hair sample from her child.
The blackmail victim had been intimidated into giving Donna Todd, 27, money on several occasions because her ex-partner was a gang member and he felt threatened.
She denied this, but was found guilty by a jury.
Justice Joseph Williams in the High Court at Napier yesterday sentenced Todd to five years and six months in prison.
She faced 11 charges for a series of attacks on her victim, blackmail, wilful neglect of a child and a prison attack caught on camera.
