Businesses receiving grants this year include AFT Pharmaceuticals, CWF Hamilton, Greentree International, Livestock Improvement, Methven, Teknatool International, and Tru-Test.
Fusion Transactive - which produces technology for petrol stations - is also among this round of grant recipients.
This company's chairman is Navman founder Sir Peter Maire, one of the directors of Callaghan Innovation.
Maire said last night that the Callaghan Innovation board was a "long way divorced from the grants side of things" and as far as he was aware the round of recipients was decided before he joined the Government body in January.
Joyce confirmed this last night and said a board from the former Ministry of Science and Innovation was making decisions on behalf of Callaghan while it was established over the next six months.
If the issue arose in the future, Maire said, he would have to step down from any relevant decision-making processes.
