STI Surveillance: Annual Report 2005

Saturday 29th January 2022


The 2005 annual report summarises STI data collected from 27 sexual health clinics (SHCs), 38 family planning clinics (FPCs) and 15 student and youth health clinics (SYHCs) across New Zealand. Data is supplemented by laboratory surveillance of chlamydia and gonorrhoea from laboratories throughout New Zealand.

  • Chlamydia trachomatis infection is the most commonly diagnosed STI in New Zealand.
  • From 2000 to 2005 the number of confirmed chlamydia and gonorrhoea cases diagnosed at SHCs has increased by 38.9% and 32.2%, respectively. Over the same time period clinic visits increased by 19.8%.
  • Young people remain at high risk of STIs with those aged less than 25 years having the highest rates of chlamydia, gonorrhoea, genital herpes and genital warts diagnosed at SHCs.

Cautionary note:
This report summarises the epidemiology of STIs, using data from SHCs, FPCs, SYHCs and diagnostic laboratories in New Zealand. The figures presented here may underestimate true infection rates because not all clinics and laboratories participate and STIs diagnosed by a range of other health care providers, such as GPs, are not included in this report. It is also important to note the denominator used in calculating disease rates. Rates based on clinic data use the total number of clinic visits, whether for STIs or other conditions, as the denominator. Rates based on laboratory data use the total ‘usually resident’ population, in the District Health Boards covered by laboratory surveillance, from the 2001 New Zealand Census.
