However, he was bemused that both trials were taking place in Canterbury.
"It's still a little bit strange to see why there needs to be two in Canterbury – there's plenty of cows throughout New Zealand – maybe the Waikato would've been a better option."
Like the Government project, Align Farms looked into the financial, environmental, animal health, milk quality and social impacts of both regenerative and conventional farming, Roberts said.
The main difference was that Align Farms' trial took place on one farm, rather than two.
"We do it on one farm but we split that farm in half so there's two herds, two milk vats, two P and Ls [profit and loss statements] and that data is compared."
He could see the pros and cons of both methods.
"[In our trial] you don't get the differences in management or differences in soil types or farm history.
"However, from an operational perspective, it's probably easier to do it on two farms so you have someone completely focused on one system."
Overall, the Government programme will cost $11.58 million, with the Ministry for Primary Industries' Sustainable Food and Fibre Futures fund contributing $8 million and Ngāi Tahu Farming and Ngāi Tūāhuriri fronting the rest.
Align Farms was owned by the Buchanan family of Central Otago and was "funded internally through profits," Roberts said.
"It's certainly not going to cost us $11.5 million; it probably won't cost us 10 per cent of that to be fair."

However, he believed the Government's $8 million would go towards "a lot of scientific trials" within the project, which Align Farms would not be doing.
Fellow farmers were "the ultimate consumer" for Align Farms and Roberts thought his trial's independence gave it credibility amongst his peers.
Trial data was "completely transparent" and loaded onto the website every week, he said.
"We feel we really need to make sure that we're giving grassroots information, that's really transparent, that farmers can relate to."
Listen to Jamie Mackay interview general manager of Ngāi Tahu Farming and Forestry Will Burrett about the Government project on The Country below:
While Roberts thought $11.58 million was "an awful lot" of funding for a regenerative agriculture project, he stopped short of saying it was a "waste of money".
He thought Ngāi Tahu's involvement would be valuable for the future of regenerative farming.
"To get a movement going you need a fast follower and Ngāi Tahu definitely are that.
"We feel there's certainly benefits in having two parties at the table comparing notes."
