Drug-buying agency Pharmac is planning to add two new vaccines for children to the National Immunisation Schedule.
The free vaccines are intended to help protect against chicken pox and the gastric infection rotavirus which hospitalises 1200 children a year.
Pharmac is proposing funding the rotavirus vaccine for all eligible patients, but funding the chicken pox vaccine varicella only for the most at-risk patients.
It is also planning to fund a different vaccine for pneumococcal disease for all eligible patients from July 2014.
An improved version of the current meningococcal vaccine is planned, with eligibility rules changed so that children with weakened immune systems receive free booster vaccines.
Public feedback is invited on the proposed changes until 20 November.
