"So much has changed since we last hosted Trenz in 2016 so we want to inspire excitement in the progress that's been made around the city and in the new products the delegates will experience during their time here," she said.
Rotorua could expect accommodation bookings from sellers and additional demand for taxis, cafes, restaurants and bars.
Businesses are encouraged to help make the Rotorua experience special by erecting chalkboard welcome signs, offering specials to delegates, ensuring enough staff are on-hand for additional demand and considering later opening hours if late licences allow it.
The week will begin with an official pōwhiri at Ōhinemutu followed by a welcome function at Te Puia on Monday.
The event is not open to members of the public and tickets can't be bought to attend.
