"I think that's partly because the way I see it is that starting a family is essentially a vote of optimism in the future but if you're a little bit uncertain about, 'Will I still have a job next year or are we going to have quite enough money to start a family?' ... some people may be delaying starting a family which has impact a little bit on market growth," he said.

A large part of the reason to move into Christchurch was to get bigger scale, Price said. "Information technology is becoming more and more important and that's expensive," he said.
"And then we have people like a scientific director for example who leads a lot of our research effort and also the innovation that we're doing and those people are not cheap."
Fertility Associates has locations in Auckland, North Shore, Hamilton, Wellington and Christchurch, and hold regular clinics in other major North Island centres and Nelson.
IVF clinics typically sell for several million dollars.
Chairman Richard Fisher said the company's investment was a commitment to the future of Christchurch and an endorsement of its views on the quality of the staff at Repromed in that city.
"We are delighted to be able to have a role in the delivery of high-quality medical care which Canterbury and the other DHBs in the upper South Island already provide."
As part of the process Greg Phillipson, a principal at the Christchurch practice, will become a shareholder in Fertility Associates.
Phillipson said: "Fertility Associates has alliances with leading research organisations such as the Liggins Institute and the Universities of Auckland and Victoria, we are delighted that our patients and staff will have the wonderful opportunities that this association can bring."
