"I accompanied delegates from Peru, Thailand and Vietnam around several farms in Northland," Mr Jamieson said.
"They were particularly interested in how Kiwi farmers maximise production from land and animals in dairying and drystock and also showed keen interest in arable farming.
"These countries also share the challenge common to most agricultural nations of attracting, training and retaining quality staff and there was a lot of interest in how tertiary institutions collaborate in New Zealand to nurture future generations of farmers."
Shortly after the summit, Mr Jamieson received an invitation from Alfonso Velasquez, on behalf of the Peruvian Government, to visit the Peruvian highlands to assess the potential to greatly improve the production of the land through changes to the infrastructure, systems, training and benchmarking.
"The Peruvian highlands are home to more than 3.7 million cattle, nine million sheep, three million alpacas, a million llamas and a variety of other species," he said.
"There is a lot of potential to improve the pasture, water quality, animal health and genetics of the region and this will favourably impact on the incomes and welfare of the Peruvian people."
The Peruvian dairy industry is on the cusp of change and Mr Jamieson said their vision of the future was being shaped by what was being achieved in New Zealand.
"I see my visit as opening the door to further collaboration with all aspects of our industry - from genetics through to milk processing, staff training and on-farm extension."
Mr Jamieson, who is a candidate in the DairyNZ board elections, is expected to return to New Zealand on Monday.
