The company has been selling off the properties, which it either bought or inherited from the former ECNZ. They ranged from houses and sections to lifestyle blocks and farms.
The property originally totalled 3100ha, The company would not reveal the prices it had received because of commercial sensitivity, but Waitaki Plains dairy farms with Fonterra shares could fetch more than $40,000 a hectare and dairy support units $20,000 to $25,000 a hectare.
Meridian estimated in 2004 it paid about $50 million for the land it bought for Project Aqua, but on present market prices it could expect to at least double its money on the properties.
Some it sold in 2008, with the latest properties, totalling almost 900ha, going on sale in September.
A Meridian Energy spokeswoman said yesterday the majority of the properties, marketed through CRT Farmlands Real Estate, had a June 2 settlement date.
The company was ''very happy with the process and sales''.
''All buyers are from within the Waitaki area,'' she said.
The last Project Aqua farm on the south bank would shortly be offered for sale by tender and strong interest was expected, because it was ''a premium property'', she said.
Meridian is considering its options with the one farm on the north bank of the Waitaki River it still owns, bought as part of investigations and planning for its north bank tunnel scheme, put on hold in January last year.
