The site will be part of Precinct's planned $681 million Commercial Bay development in downtown Auckland.
The development will encompass Precinct's four buildings in the surrounding area - PwC Tower, AMP Centre, HSBC House and Zurich House - and will be worth about $1.5 billion on completion, representing 63 percent of the property investor's portfolio, it said in a statement in December.
Fletcher Building has been hired for the Commercial Bay development, with work expected to start in June this year, including construction of tunnels under the precinct for the city's rail link.
The retail centre is expected to open by October 2018, with the office tower completed by mid-2019. The company's Auckland Wynyard and Commercial Bay developments will increase its gearing to about 35 percent from 12.5 percent at present.
Precinct shares rose 0.8 percent to $1.225, and have fallen 2 percent so far this year.
