Thelning Design Innovation (TDI) was created in early 2016 as an endeavour to offer New Zealand customers (primarily) the opportunity to benefit from innovative design and effective engineering solutions. The TDI team wanted to distinguish themselves by offering high level technical skill while maintaining value and support. TDI are a small group of highly skilled mechanical engineers, whose combined experience presents a unique diversity which is necessary for true innovation and invention. TDI’s innovative design can be applied within any industry which may require the particular skills of a mechanical engineer.
