Campbell said Quadrant has implemented "very impressive" improvements to Summerset's operational efficiency and capital structure, and he is confident about its future as the country's population ages.
"The growth prospects ahead are, in fact, very good. The demographics certainly support increasing demand for both retirement villages and in the managed care end of the business," he said. "Both are going to be very strong in the future, and it's becoming harder and harder for the smaller players to compete in these areas."
Summerset is New Zealand's third-biggest retirement village operator, though it has the second-fastest pace of construction.
The retirement village operator made a loss of $1.8 million in the 2010 calendar year after booking a $5.9 million tax charge, compared to a profit of $1 million a year earlier.
Operating profit rose 8.7 per cent to $7.5 million on a 39 per cent surge in revenue to $34.2 million, while finance costs almost halved to $3.4 million.
Quadrant successfully floated Kathmandu Holdings on the NZX and ASX in 2009, raising A$375 million for the first float on the New Zealand exchange in 22 months, and last year bought Asia Pacific media intelligence agency Media Monitors Australia.
