Sexually transmitted infections (STI)

ESR undertakes STI surveillance on behalf of the Ministry of Health. A number of different surveillance systems are currently in place including notifications, laboratory-based surveillance and clinic-based surveillance.

These reports present data on chlamydia, gonorrhoea, genital herpes, genital warts, syphilis and non-specific urethritis (males only), chancroid, granuloma inguinale, and lymphogranuloma venereum cases reported for the quarter from sexual health and family planning clinics across New Zealand for the period 2003-2018.

From 2019 quarterly syphilis, gonorrhoea and chlamydia reporting is in a dashboard format here. All other clinic data will be reported annually. Below are the archived reports, if you want to see reports from the last five years you can return to the main STI surveillance page.

Cautionary note:

The number of cases of STIs reported through the clinic-based surveillance system underestimates the true burden of disease in New Zealand because a substantial percentage of STIs are diagnosed by other health care providers, particularly primary health care practitioners.
