Many Maori don't feel comfortable discussing sexuality and sexual health, says Family Planning Association national medical adviser Christine Roke.
Ms Roke says the association's annual conference this week is considering questions such as rates of contraception and sexually transmitted diseases in various age groups and communities.
Maori have a high rate of accidental pregnancy.
Ms Roke said shyness about discussing family planning may be a factor. "I think that younger Maori often don't have quite have the same concern that older Maori might, but it's still there," she said.
