AUCKLAND, New Zealand - Navman has finished a major expansion in Northcote that doubled the size of its electronics manufacturing space.

The company, which is owned by Brunswick Corp., a U.S. company, designs and builds marine, wireless data and personal and car navigation systems.

The company spent more than 12 months and NZ$4 million on the expansion. The company employs 450 staff in Auckland.

The 85,000 sq. ft. campus is more than twice the previous size.

In a statement, Brunswick chief executive and chairman George Buckley said Navman "is on track to achieve $400 million this year" and NZ$1 billion within three to five years.
