Work was then allowed to continue so the company could achieve its goal of delivering water to landowners this growing season.
Keeling said the delayed work was finished in early December, but further delays had occurred since.
"The works at the dam has now all been approved and is undergoing commissioning this week."
All the council's deadlines had been met so far.
Farmers in the command area had coped well with dry conditions in December and ''really appreciated'' the rain that fell before Christmas, he said.
"However, the incessant hot, dry conditions are taking their toll on-farm and it would be fair to say most of our farmers are under pressure."
The company had sold a few extra shares to some existing shareholders as they finalised the watering systems on their properties, Keeling said.
The project was replacing about 44km of open canal with 37km of underground pipes, taking irrigation water from Lake Waitaki rather than from tributaries further down.
It would also increase irrigation coverage from 1983ha to a potential 5500ha.
All the pipe-laying had been completed just before Christmas and about 30 people were working on the project through the summer.
"Since early January they have been working on installing on-farm points of take, finishing fencing around air valves and other infrastructure."
Dry commissioning of pump sheds and associated works was also being carried out, Keeling said.
