Who is this for?

This service is for people in Aotearoa New Zealand who have been diagnosed with a sexually transmitted infection and want to let sexual contacts from the past 3 months know they may need a check-up.

Many STIs have no symptoms. Partner notification helps prevent reinfection and stops further spread.
