A small firm with a long track record.

WiMac Infrastructure Advisory was established to give councils and road controlling authorities access to senior, commercially grounded advice without the overhead of a large consultancy. We work from North Canterbury with clients across New Zealand.

How we work

Practical first. Advice grounded in what can actually be delivered, funded and defended.

Direct and honest. If the answer is uncomfortable, you’ll hear it early, with options.

Quick to respond. No bureaucracy between you and the person doing the work.
