Mr Chow had previously told the Rotorua Daily Post he and his brother Michael saw Rotorua as a safe investment bet because of the rocketing tourism numbers.
He said they were also looking at other investments around the city.
The Chow brothers formed Chow Group in 1999 and own 16 other commercial properties, mostly in Wellington and Auckland.
They were once known as the "brothel brothers" after putting in plans for a super-brothel in Auckland. The 15-storey Palace Hotel fell victim to fire in 2010 and was eventually demolished.
They decided against going ahead with the super-brothel and put the land back on the market. They also own two clubs on Auckland's Karangahape Rd and Gore St.
