Instead, the company has set up a hybrid inhouse model - a 60:40 owned manufacturing company, PowerShield Solutions, drawing on the expertise of David Todd, the founder and former majority owner of PowerShield's contract manufacturer, Quick Circuit.
Todd said there's little incentive for a contract manufacturer to reduce costs because it will reduce their sales figures, a dilemma solved by a joint venture arrangement where both benefit. He's confident of reducing PowerSheild's production and supply chain costs by 30 percent within a year.
"That's quite significant," he said.
On paper, the Chinese and Malaysian contract manufacturers may offer a slight lower unit cost, but companies have to consider the total cost of ownership of their product, including having to fly in engineers to fix problems and difficulties monitoring quality, Todd said.
One of the biggest intangible benefits will be the company's design engineers working face to face with the production staff. PowerShield's previously high stock inventory could also be reduced by better direct communication between the manufacturing and sales operations.
Manufacturing NZ executive director Catherine Beard said rising labour costs in China and the difficulty of protecting intellectual property had caused a number of kiwi companies to rethink offshoring in the past two years. Another factor was the previously high dollar, which had allowed companies to invest in new, more efficient plant and equipment that may have been too expensive in the past.
The hollowing out of New Zealand's manufacturing industry has left a skills shortage, Beard said, with an Export New Zealand survey due out soon showing nearly 69 percent of respondents were experiencing difficulty finding enough qualified staff.
Set up in 1997 by majority shareholder and non-executive director John Grant, PowerShield monitors and manages mega-banks of batteries that are pulled into service in the event of a power outage at critical infrastructure. That guarantee of back-up power is crucial for emergency communications for customers in 30 countries such as Whitehall's Ministry of Defence or the San Diego Sheriff's department. Call centres, which are growing worldwide, now account for around a third of its annual revenue, which sits between $5 million and $10 million.
PowerShield's system monitors whether individual battery cells, often numbering into their thousands at one site, and the system as a whole, are working. The data transmits daily to PowerShield's secure server and it also has a remote reporting service that gives customers detailed analysis so they're alerted of any potential dangers and the need for preventative maintenance.
In New Zealand PowerShield monitors the batteries for Meridian's wind farms, Genesis Energy's Huntly power station, Auckland Watercare's urban water reservoirs, the Department of Internal Affairs, and SkyCity's casinos.
