Ashburton is set to host the New Zealand Secondary Schools Netball Championship for the first time.
Sixteen of the best high school teams from around the country will compete at the new EA Networks Centre over a week in October.
EA Networks Centre Manager Steve Prescott said the event was "often the most highly anticipated tournament of the season".
"Events of this size have a huge impact on our local economy. People spend money on food and accommodation while they're here. It will have a great flow-on effect."
Netball NZ Chief Executive Officer Hilary Poole said the opportunity to hold a national event in Ashburton was exciting.
"To take the NZSS event to the new EA Networks Centre is a coup for both Netball NZ and for the town and we know the teams will warm quickly to the Mid Canterbury hospitality," she said.
The EA Networks Centre is also about to host 80 swimmers at the annual South Island Masters Short Course Championships. The event will be held on 18 and 19 September in the Centre's main 25-metre pool.
Mr Prescott said Ashburton had not hosted the South Island championships in recent years, so it was exciting for the district. Swimmers from Nelson to Queenstown have entered in the event.
Last week, the Zone 4 A Secondary Schools Basketball Premierships - the qualifier for the National Secondary Schools Championships - were held over three days at the EA Networks Centre, attracting 24 teams and hundreds of supporters.
