Better Breathing programme lead Eileen Hall said internationally accredited assessment tools showed participants had an improved quality of life, among other health outcomes.
"Participants also benefited from social interactions with others who have the same challenges, with some participants even forming their own support networks," she said.
Hall said many people experiencing breathlessness need to improve their exercise tolerance.
"It's very slow and it's very patient dictated, but what we find is that over the eight weeks people can do more exercise, for longer, and become more independent and self-confident," she said.
The DHB runs group sessions in Napier, Hastings, Central Hawkes' Bay, Wairoa and virtually via Zoom. Group sizes are limited to 20.
General practice or specialist teams can refer heart or respiratory disease patients with reduced exercise tolerance, or those who have difficulty coping with daily activities due to breathlessness, to the programme.
