Former Prime Minister Helen Clark is reported to be on the shortlist to head a global organisation that fights diseases.
The New York times reports Ms Clark is one of three finalists to become the director of the Global Fund to fight Aids, Tuberculosis and Malaria.
Donor countries support the fund, which receives around $5 billion a year.
Ms Clark is standing down from her current position with the UN when her term ends in April.
She's been head of its Development Programme for eight years.
Last year she lost her bid to become the next UN Secretary-General, which went to Portugal's Antonio Guterres.
