Rakon has signed a deal with the Chinese technology firm Huawei to supply components for infrastructure equipment and smartphones.
Rakon, which makes electronic components for global positioning systems and mobile phones, expects the deal will be worth at least $US56 million over the next five years.
Chief executive Brent Robinson says the company has been working for a number of years to position itself to supply to Huawei.
Huawei currently accounts for about 2% of Rakon's supply and the deal aims to quadruple that.
Rakon will also be supplying frequency control products to Huawei, which operates in more than 100 countries and has been in New Zealand since 2005.
