John Holt, the website's founder and chief executive, said the deal would fund the 18-month-old business to a break-even position and allow it to grow.
"Our focus on homeowners who are not buying or selling will increase as we add a wide range of calculators and tools to help manage your home and enhance its value. Helping Kiwis plan for their longer-term property aspirations and significant projects on their current home is all part of our vision of being much more than just a property listings portal," Holt said.
When the site was launched last year, homes.co.nz's Jeremy O'Hanlon said the details of 1.2 million New Zealand residences, flats and apartments were accessible, giving up-to-date valuations on each residence and its site.
"These are all things you've had to pay for in the past," O'Hanlon said, explaining how the information was drawn from authorities including councils, which hold property records. "We've got the sales history, estimated value and we're now working with Westpac and IAG to add new data sets."
The site's computer model uses the data, historic sales and trends in each area, which is updated monthly, to give people an idea of an estimated value. Property sales history, recent sales, monthly homes estimate and rating values are on the site.
