Children in Tokelau have been worst affected by a flu outbreak which has so far infected 10 percent of the islands' population.
The Ministry of Health says about 150 people, most of them children, have contracted the influenza-like virus.
A Wellington Hospital Nurse, Bronwen Markham, who's heading to Tokelau says children are more prone to contract the illness because of their hygiene habits.
She says she and an official from World Health Organisation are expected to arrive in Tokelau by Thursday to deliver about 1400 flu vaccinations.
