As part of a region-wide rollout of 20 kits, Queenstown and Arrowtown have two additional defibrillators for public use.
Queenstown Library manager Robyn Robertson and Lakes Leisure facilities general manager Cam Sheppard accepted the automated external defibrillators from St John Southern Region training delivery manager, Shirley Kerr, last Wednesday.
One will be kept on the wall near the front desk in the library.
The other will circulate between Queenstown Memorial Hall, Arrowtown Athenaeum Hall and the Arrowtown Pool, as events demand.
The defibrillators, which are smaller than laptop computers, use an automated voice to tell an individual how to apply the equipment to a person having a heart attack.
The defibrillators could save a heart attack victim's life while an ambulance was on the way.
The 20 kits were purchased usingf a $100,000 donation from the Dunedin-based Marsh Family Trust last month, and are being distributed around Otago.
St John is providing the training, and will help choose where the defibrillators will be kept for maximum community benefit.
Lakes Leisure facilities general manager Cam Sheppard and Queenstown Library manager Robyn Robertson thanked the trust and St John.
"It gives our staff a better ability to respond in an emergency situation, should one arise. It adds to the defibrillator already at the events centre, and the first aid training all staff get," Mr Sheppard said.
