Police are offering a $20,000 reward for information that could help locate missing Christchurch woman Tisha Lowry.
Investigators say they have few leads over the disappearance of Ms Lowry, 29, more than eight months ago.
She was last seen in Aranui on 25 September 2008, after she had been to the Bower Tavern with her grandfather.
Detective Senior Sergeant Virginia Le Bas says someone holds the key to her disappearance.
The reward is for information or evidence that could establish Tisha Lowry's location or that of her body, or which leads to the conviction of anyone responsible for her disappearance or death.
