"We could not have achieved this without Landcorp - they have done a great job.
"This event celebrates that transformation and the friendship and respect which have been generated over those years, and which will endure beyond the end of the Joint Venture."
Mr Lee said he hoped the future would include opportunities where Landcorp and Milk New Zealand could again work together on mutually beneficial projects. This intention was reflected in a future-focused friendship agreement.
Justine Kidd, CEO Agribusiness for Theland Tahi and Purata (South Island) Farm Groups, said the company is now looking to build on the work Landcorp has done.
"We have an interesting and diverse farm asset in the Tahi Farm Group and this presents both opportunities and challenges," said Ms Kidd. "Our underlying strategy is to grow our asset value, with the asset being described as our people, our community, our environment and our farms.
"We are very focused on understanding where the opportunities are to improve our productivity, how we can keep producing great quality milk for our consumers in New Zealand and China while improving our sustainability and enhancing the impact we have in our local communities and environments.
"The dairy industry is facing continual change and the continual improvement culture that the Purata Farm Group has led will be fundamental to Tahi leading positive responses and positive outcomes as we navigate the changes and challenges in front of us.
"It is easy to focus on the environmental regulation but we really see that these challenges and changes are about farming in a wider community and ensuring what we do enhances that community, economically and socially.
"We are creating a nationally-led and nationally-focused business, so the Purata Farm Group and the Tahi Farm Group will operate as one business. This provides us with wonderful opportunities to grow our people across a wider business that can provide new challenges for individuals as they grow in their career with Theland Farm Group.
It also enables us to share and learn from each other and our different farm assets and the different places that we farm."
Ms Kidd said the farms will largely have farm managers in place, with six of the eight management roles taken up by the existing farm managers who worked with Landcorp and one by a Purata team member who is taking on his first management role.
"We also have four new business to business opportunities which have offered three new contract milking roles and one 50/50 sharemilking role," said Ms Kidd.
"We are very excited about the team that is joining us from June.
"Theland Farm Group is looking to add value.
"We will continue to seek out opportunities to add value to the people who work with us, to the land we farm and the communities we farm within."
