A man who blames Coca-Cola for his wife's death is reportedly making angry phone calls to the company's Invercargill branch, prompting warnings for staff to take care.
Natasha Harris, 30, drank eight litres of coke a day until her death in 2010.
Fairfax is today reporting that her partner Christopher Hodgkinson made several calls to the company one day last week.
He blames the soft drink giant for what happened and in the phone calls he asked Coca-Cola to help him get his eight children back.
Mr Hodgkinson said Coke gave him the "royal run around" on the phone. He admitted he was angry but said he hadn't threatened anyone.
Fairfax reported that Coco-Cola had since sent photographs of Mr Hodgkinson to its staff so they know what he looked like.
He also reportedly made threats against staff at the company four years ago.
The coroner who probed Ms Harris' death found Coke consumption contributed to her death, but the drinks company argued its product wasn't linked to her death.
Coroner David Crerar ruled Ms Harris died of cardiac arrhythmia caused by poor nutrition and the effects of caffeine.
