The two subsidiaries contributed $213,000 in income to Innovation Waikato, but cost it $173,000 in expenses.
Dairy Solutionz and Beef Solutionz are focused on helping agricultural firms expand export sales and plan to set up at least three farms by the end of 2013.
But Mr Fairweather said the spend was justified, and could not be compared to the airport or hotel group.
"When you are doing something that is innovative and first to market, having the calibre of people is important.
"We are closing $100 million of deals. None of your businesses have ever put in that level of growth."
Mr Fairweather said the business would begin to pull back on the level of money and type of directors now the subsidiaries were both trading.
The group, which runs Innovation Park in Ruakura, reported both office buildings were fully tenanted and work on a third office building was earmarked for next year.
Innovation Waikato has previously estimated it would need $142 million to transform the farmland into a 19-building park.
The last building cost $9 million and opened in mid-2009.
Last year Hamilton City Council converted its $2.4 million loan to a 19.8 per cent share in Innovation Waikato. The council agreed in October to sell its shares to Eden Agricapital which is now trying to raise capital.
Mr Fairweather said the council could start budgeting that it would get its money back, but there was no set date at this stage.
Innovation Waikato's other shareholder, Katolyst, holds the remaining 80.2 per cent and this trust is also linked to the city council.
