Baumann, former two-time Olympic gold medallist in swimming and head of Canada's Own The Podium high-performance sports programme, said coaching is the top priority for HPSNZ.
"If you have the best coaches in the world, then your athletes have a much better chance of performing at the highest level," he said. "Coaching is all about the athlete, and the right coaching is about making sure coaches deliver what's needed to maximise success for that athlete or team.
"HPSNZ is prioritising resources for the development, recruitment and retention of high performance coaches, because we believe the quality of our coaching can be an area where New Zealand stands out against the rest of the world."
Most of Henry's work with HPSNZ will have a longer-term focus. He will take on a mentoring role with targeted coaches and will work with HPSNZ to help national sport organisations build the leadership capability of their high-performance coaches.
"It's crucial for coaches to be effective leaders, so hopefully sharing the knowledge gained from my coaching experiences will help New Zealand's coaches provide the leadership and coaching their athletes need," Henry said.
