Rakon, an Auckland-based supplier of crystal oscillators for global positioning systems, posted a first-half profit after sales and market share rose.
Net income totaled $5.6 million in the six months to September compared with a $6.2 million loss in the same period a year ago. Sales rose 31% to $94.6 million.
Rakon is expanding production in response to demand for oscillators which are used in smartphones and are a key component of femtocells, used by companies such as Vodafone Group Plc and AT&T to improve mobile network coverage.
The company will open a plant in Chengdu, western China, in mid-2011, while its plants in India and Britain have doubled their capacity.
The first-half result extends a recovery from 12 months ago when sales were hit by the global financial crisis, chief executive Brent Robinson says.
