While the funds will help, Avery said donors were actively being sought to fully fund the $28m project.
The institute, located at the Hawke's Bay Regional Sports Park, will open on Monday, July 8.
Facilities include the indoor sports centre, a community health and fitness gym, dedicated sport and health clinic, teaching, research and conference facilities, and a cafe.
"A variety of programmes already being delivered to schools, clubs and communities from Wairoa in the north to Waipukurau in the south are having a noticeable impact on people's lives."
"We want to build on this and to do so it is critical that we raise the funds to complete the next stages of the plan as soon as possible."
Further support for the full development of the main building and the Accommodation Hostel is still required.
An additional Health Wing is also planned and support for that is currently being sought.
