Centuria Capital has boosted its international platform, with its $122 million takeover offer for Augusta Capital going unconditional after it secured 65.86 per cent of the New Zealand property company’s shares late on Wednesday.

The deal now sees Centuria on track for a full takeover of Augusta, which, if completed, will increase Centuria’s assets under management by 24 per cent to $8.9 billion.

Joint Centuria CEO John McBain said he was "delighted" to report close to two-thirds of Augusta shares have been secured within eight business days of the takeover offer commencing.

"We are encouraged by the significant response and look forward to the offer completing, which will expand our funds management platform into the New Zealand market," he said.
