The consortium and the council entered into exclusive negotiations over that project last month.
Forsyth Barr Research said last month that Augusta Capital was making good progress changing its business model from owning properties itself via direct property investment to funds management.
The key focus for Augusta was getting its balance sheet utilised so it could replace the rental income lost from property sales, it noted.
"Recent periods have shown record activity levels, and growing earnings off this high base is challenging. We are confident of management's ability to transition Augusta to being solely a funds management company over time, albeit earnings will have some
volatility through this transitional phase. Augusta's fund's management business makes it very different from the other listed property vehicles and gives it less capital intensive growth prospects, albeit at higher risk," Forsyth Barr Research said.
It listed in December 2006 as Kermadec Property Fund but in March 2012, it bought the funds management businesses from Augusta Funds Management and internalised its management structure.
In April 2014, it bought KCL Property for $15m, which increased total property under management by about $750m to around $1.6bn.
Augusta is now changing its business to focus solely on funds management by selling its directly owned properties.
Forsyth Barr listed risk factors to its business as an economic slowdown, rising interest rates, or a decrease in investor sentiment.
