It has taken on seven staff in the last three months, bringing it to a total of more than 30 employees in the region.
Peter Cameron, managing director of AVG A/NZ, said sales revenue for April 2009 was 115 per cent higher than in April 2008.
Overall sales results for the first quarter 2009 showed a 101 per cent growth over the same period in 2008.
"We've achieved excellent results in the last financial year, with many months of record sales," he said.
Preliminary figures show that AVG A/NZ achieved just over 63 percent sales revenue growth for the full 2008-2009 financial year.
"Our market is primarily consumers and small to medium enterprises (SMEs)," added Cameron.
"We are very focused on those sectors with carefully tailored offerings that meet their security needs at a very affordable price.
"The expansion of our Client Care teams has enabled us to continue to provide service and support of the highest calibre to our clients and resellers. Unlike many of our competitors, there is no charge for this support for our commercial clients," said Cameron.
AVG A/NZ operates a multi-tiered distribution strategy, working with more than 2350 resellers, plus major corporate partners, to roll out its security solutions.
The company has found that the combination of its technology, local support services and AVG Technologies, make an attractive package for companies interested in offering trial versions of AVG to their customers.
It recently announced partnerships with Suncorp Bank and 3 Mobile Broadband.
Cameron said the company is also just coming to the end of the first stage of a managed business expansion programme.
"We've added seven new personnel in the past three months. The extra people, combined with other systems and operational changes, have allowed us to extend our service and support offerings and further enhance the way in which we touch our customers and channel partners," he said.
