"This is a highly successful, well-run business, but it has been doing things the same way for a number of years.
"My brief is to stand back and take a good look. It's about driving efficiencies, increasing our ability to benchmark across the business, and letting people do what they're good at."
Realty Services chief executive Ross Stanway said Mr Young had the qualities the company was seeking in terms of understanding the real estate business and having performed in a similar role.
"We see him as someone who will fit well with our people and business."
Former boss Nick Hargreaves, chief executive of Jones Lang LaSalle, said Mr Young had been thought of by staff as approachable and user-friendly.
"Above all else, he doesn't flap," he added.
Mount home choice about family
Heath Young and his wife Jane spent three months checking out Tauranga's residential property market before deciding to live in Mount Maunganui.
Mr Young is a keen golfer and runs to keep fit, while his wife also golfs and practises yoga, and the family enjoy the beach lifestyle.
The couple have three children, two girls aged seven and five, and a five-month-old boy.
"The golfing was going real well till five months ago," said Mr Young. "But now we're largely focused on the young family."
After six weeks in the Mount the couple are enjoying the fact that there are nowhere near the traffic problems of Auckland.
"Having lived here 15 years ago, I've noticed some real changes," he said. "Tauranga's growing and it's got some really good things going on. And the Mount has been through a real renaissance."
