Forbes has valued Khosla's personal fortune at US$1.3 billion.
Last month his company launched a new, US$1.05 billion fund that is largely aimed at supporting early stage, clean technology companies.
It is Khosla's fourth major fund and one of the top five largest new venture funds launched this year, according to the Wall Street Journal.
Nick Gerritsen, co-founder of Carbonscape, said the Blenheim company - whose technology turns sawmill waste into valuable products including carbon, syngas and bio-oil - was looking for an investment of $3 million to $4 million which would take the firm to the point where it could start earning revenue.
"If he says 'go' it's really going to transform the company," Gerritsen said.
LanzaTech's co-founder and chief scientist, Sean Simpson, has said the US$3.5 million the company received from Khosla Ventures in 2007 was the firm's first "big break".
"That really opened up a whole different world of investment opportunities ... because we were not trapped in the small pond that is funding sources from within New Zealand," Simpson said last year.
LanzaTech announced yesterday that it had secured its first commercial customer.
The Business Herald understands that Khosla will visit the biotech company's research facilities in Auckland during his visit.
Windflow Technology chief executive Geoff Henderson said Friday's pitch was a big opportunity for the Christchurch-based turbine maker, which narrowly escaped liquidation last month when an investor agreed to underwrite a $2 million capital raising.
"You don't get the opportunity to make a pitch to a person of Vinod Khosla's net worth very often," Henderson said.
Khosla told Bloomberg last month that through supporting early stage clean-tech companies developing unproven technology, he expected some to fail.
"We do a lot of very high risk, early investments," he said.
"We'll invest a million or two and we might fail at it, but if it works then we'llput $10 million, $20 million, $30 million init."
Khosla Ventures' clean-tech portfolio has already made profits of more than US$1 billion, according to Bloomberg.
