"We're going to get massively more than that."
According to WREDA, a number of candidates currently hold senior roles at major tech brands including Facebook, Google and Amazon.
Jones said to the best of his knowledge, the concept is the first of its kind anywhere in the world, with candidates filling out an online profile and the best picked to fly to Wellington - with by far the most interest coming from the United States.
"I think the measure of the response is evidence this hasn't been done before," he said.
"About 35 per cent of [applications] are from the US, but below that you've got India, Brazil, Philippines, UK, Singapore, Pakistan, South Africa, Canada and Croatia - they're the top ones."
Jones said provisional estimates had the economic impact somewhere close to $5million for Wellington in 2017.
"Specifically about the people who get put into those jobs and take an average salary, we calculated that at about $4.8m," he said.
"But that's only a small amount of what is going to happen, because ideally, those people will help Wellington companies grow their business and there'll be other economic multipliers at play."
A collaborative talent-attraction programme, WREDA teamed up with Immigration New Zealand, international recruitment agency Workhere New Zealand which is also conducting pre-screening of candidates, and TechNZ - the New Zealand Technology Industry Association.
The programme is open to all New Zealand businesses with tech operations in the Wellington region and there is no cost to employers to participate until they make a hire as a result.
The cost associated with a successful hire is a flat fee that is "significantly lower" than market rates for conventional recruitment for mid to senior-level IT professionals. More than 20 employers are already signed-up including Xero, TradeMe and Weta Digital.
Jones said he had already been in contact with economic development arms in Auckland and Christchurch as a result of the Wellington scheme's early success.
Earlier this month a privacy breach forced WREDA to shut down the website, after personal details of potential interviewees failed to be kept secure.
