If re-elected, National says it would ensure that 95% of all eight-month-old children are fully immunised with three scheduled vaccinations by the end of 2014, an increase from the present target of 70%.
The policy, announced on Thursday, is aimed at tackling diseases such as whooping cough.
The party's health spokesperson, Tony Ryall, said the target of having 95% of two-year-olds fully immunised by the middle of next year was on track to being achieved.
In its broader health policy, has pledged free after-hours GP visits for under six-year-olds and says it would roll out a $12 million nationwide rheumatic fever programme targeting communities vulnerable to the disease.
