The International Union for Health Promotion and Education (IUHPE) conference will start in Rotorua this Sunday.
The event, which runs from April 7-11, is the largest international conference that the city has ever secured.
More than 1200 delegates from around the world will come together over the five days to discuss best practice in health promotion, research, and theory.
Destination Rotorua business events manager, Craig Murray, said it was a great opportunity to showcase Rotorua's ability to host large conferences and provide a high-quality experience.
"An event of this scale involves many of our hospitality and visitor industry operators, as delegates will have opportunities to explore Rotorua and enjoy some of the restaurants and attractions on offer.
