Shares in Orion Health began trading at $6.50 on the NZX today after its $125 million float.
The float was the 13th this year and the opening price was 14 percent above the issue price of $5.70 per share.
Orion Health chief executive and majority stakeholder Ian McCrae said the listing and capital raising opened many more opportunities for the company to grow its market share and expand its product offerings.
"What we have to do is be a good company, develop good products, and I suspect the share price looks after itself then," he said.
"We already had two or three hundred shareholders, now we have a whole lot more, so that's a pretty big responsibility for us to actually look after them and make sure we grow the company's value, so it's a big responsibility."
