Ms Hartley was admitted to hospital on 1 August while on her second honeymoon in Bali.

She had a twisted bowel and contracted a blood infection while on holiday, and fell into in a coma.

She had not disclosed the condition to her travel insurance company and it refused to pay for her care.

But a Givealittle fundraising page raised more than $237,000 to help cover her hospital bills and a Medivac flight home.

National Party leader Simon Bridges said Ms Hartley's husband told him over the weekend that she had died.

He offered his condolences to her family.
