There's a recommendation schools put clearer relationship and sexuality education in place.
An Education Review Office report has found too much inconsistency in what students are learning.
It calls on secondary schools to increase sex-ed teaching and tell parents what will be taught, rather than consulting them.
It also found young people are being exposed to risks, particularly online.
Education evaluation centre lead Ruth Shinoda says the curriculum should be revised.
She told Heather du Plessis-Allan that schools should be required to inform and explain to parents what they’re going to teach, as they found that parents are more comfortable with the curriculum when they’re better informed.
