This vision got a further breath of life in March last year, when the Prime Minister's Chief Science Adviser, Sir Peter Gluckman, officially opened the new premises of Nextspace, the first technology company to move into the area.
"It is not possible to imagine any way New Zealand can succeed in a world where knowledge-driven innovation will be the major source of economic growth unless a real innovation ecosystem develops in Auckland," Sir Peter said.
Mr Kumar's call to New Zealand tech companies to cluster together in Auckland got a predictable response from down the line, with Wellington-based tech CEO Bruce Aylward claiming there was already a Silicon Valley in Wellington and had been since 2006.
He made the eminently sensible suggestion that with a population the size of a small United States city, New Zealanders shouldn't be parochially poking our tongues out at each other, we should be developing the whole country into one Silicon Valley. Pool our resources and work as a team.
I'd always thought this was a key justification for the Government's multibillion-dollar ultra-fast broadband rollout. So whether you lived in Gore or Wellington or Auckland, access to the new fibre-optic cable effectively turned the whole country into a virtual Silicon Valley. Techies wouldn't have to debate the merits of living in sunny, cultural Auckland versus wet and windy Wellington. They could chose whichever city they preferred.
As for pinpointing an approved site for the Silicon Valley of the South Seas, short of giving politicians much greater powers to direct economic development - and no one has an appetite for that sort of a command economy - such visions don't have a great track record of coming to pass in this city. Sir Bob's old stamping ground out west had dreams of becoming both the film capital and, at Hobsonville, a major boatbuilding centre. The market ordained otherwise in both cases - for now at least.
The emergence of an Auckland mini Silicon Valley will succeed or fail for similar reasons. Not because a politician thought it a good idea, or a tech pioneer was feeling lonely and needed some like-minded company, but because it made economic sense. Which is why mid-Queen St is now Fast-food Valley.
Creating labels like Silicon Valley or Cultural Capital, and presuming it will happen - or is true - seems to be doing things in the wrong order. These are labels to be attached, at best, after the event, not before. But in a country, where a third of the population lives in one place, such labelling seems pointless and divisive. By sheer weight of numbers, Auckland is going to win the crown.
As Mr Aylward highlighted, by both population size and GDP New Zealand is just a flyspot on the world economy. A little ribbing between different centres is fine, but competing for meaningless titles does seem unproductive and self-defeating.
