The Government is making free flu vaccinations available to more people.
It says children aged between six months and five years who have been hospitalised for respiratory illness or who have a history of significant respiratory illness will now be eligible.
That is expected to involve about 7000 more children, costing an extra $1.2 million over five years.
Others eligible for free flu jabs are people aged over 65, pregnant women and those with ongoing health conditions or heart problems.
Health Minister Tony Ryall says children with respiratory illness are most at risk from serious complications from flu.
