The Sydney-based company will have spent $22 million on the former Mount Aspiring Hotel when the development is completed.
Speaking from Sydney, Mr Robinson (45), who managed Quality Hotel Dunedin in his early years in hospitality at the age of 27, said Wanaka appealed to Wyndham's vacation ownership club travellers.
He likened Wanaka to the "old Queenstown" with a quality village-type environment.
The Wanaka development would be completed on September 20.
Wyndham bought half the Mount Aspiring Hotel from businessman Graeme Wilkinson, spending $12 million on building 31 units, a pool, hot tub, gym, steam room and barbecue area.
It then completed the purchase of the full complex and is spending $10.3 million on refurbishing 30 studios and, in the new garden block, building three deluxe units and three presidential units which Mr Robinson said would rival anything in New Zealand for quality.
The former New Zealander carries an Australian accent these days but his heart is still on this side of the Tasman and he is looking forward to being in Wanaka in about two weeks to catch up with friends and colleagues.
Mr Robinson said market research showed the luxury end of the market was running at 98% occupancy in Wanaka.
"There is demand for our product.
"We have been in New Zealand for three years and have gone from no owners to 4700 New Zealand owners."
The company, which is part of the New York-listed Wyndham Worldwide Group, established itself in Australia eight years ago and now claimed 43,000 "owners" of its vacation properties which operated similarly to time-share properties.
Mr Robinson has been managing director and chief executive since 2003.
The recession gave Wyndham the impetus to examine its operation and start positioning itself for the upturn in growth.
The restructuring had proved very effective, he said.
The last financial year, which ended in December, was the best on record for Wyndham Vacation Resorts, with revenue of $A200 million $NZ250 million) and earnings before interest, tax, depreciation and amortisation of $A32 million.
However, the company was trading ahead of last year at comparative periods, Mr Robinson said.
"Things are tough and we cautiously redefined our business.
"We downsized the company and are now much stronger.
"It's all about having the right team."
Wyndham was keen to expand in New Zealand.
It managed more than 100 rooms in New Zealand across two properties in Rotorua and Wanaka and with an associate resort in Paihia.
Mr Robinson was always looking for expansion opportunities in New Zealand, particularly Wanaka.
The joint initiative between New Zealand Prime Minister John Key and Australian Prime Minister Kevin Rudd on easing cross-border activities between the transtasman neighbours was a positive sign for the tourism industry, he said.
