Shanahan said one of the most encouraging signs was the growth in scale many firms were showing.
"Thirty per cent of TIN100 companies have revenues of over $50 million for the first time," he said. "The group of companies with revenues between $50 and $100 million also grew by 15 per cent this year."
Shanahan said the revenue growth was evidence of a maturing technology sector increasingly defined by larger, more capable companies.
The growth was expected to continue, he added.
The report said the IT services and support sector delivered the strongest dollar growth with revenue increasing by 11 per cent.
Healthcare was the next fastest growing sector, with sales passing the $1 billion mark.
Spending by the TIN100 companies on research and development also grew by 15 per cent, while employment in R&D jobs increased by 16 per cent.
NZX-listed whiteware manufacturer Fisher & Paykel Appliances was ranked number one this year in terms of sales, with a revenue of $1.12 billion.
Kiwi IT giant Datacom Group came second with revenue of $725.2 million, while medical technology maker Fisher & Paykel Healthcare came third with $506.1 million.
