About $7.75m has been kicked in by industry this financial year, with contributions to increase in the coming years and as more partners sign on.
"We are committed to reducing agricultural emissions and for this, we need to get new tools and technology into the hands of farmers as soon as possible," O'Connor said.
"This represents a new and exciting way of working. By working together, we can help farmers shift the dial sooner.
"New Zealand can be, and should be, a leader in developing innovative new tools and technologies to reduce emissions on-farm, and be the one other countries can look to."
The centre was announced as part of the $338.7m in funding over the next four years to for new tools and technologies to reduce agricultural emissions.
The agriculture sector contributes 50 per cent of New Zealand's gross greenhouse gas emissions and around 91 per cent of biogenic methane emissions.
The Government has committed to a net-zero target for 2050 and reducing biogenic methane emissions by 10 per cent by 2030, relative to 2017 levels, and 24 to 47 per cent lower by 2050.
