Independent NDT Limited began business in January 2001 to perform third party non destructive testing (NDT) on down-hole drilling inventory. Independent performs inspections from the crown to the drill bit, and has been performing preventative maintenance inspections for New Zealand drilling operators since the company’s inception.
Independent NDT Limited has grown from a one-man operation, to a staff of seven trained NDT inspectors. This has allowed Independent NDT Limited to pursue a greater scope of operations within the industry in New Zealand. Each year Independent NDT Limited has shown strong growth. This trend is certainly not slowing down.
