Rock solid investigations and reviews
WELCOME TO BASALT SOLUTIONS LTD
Whether it’s an allegation of staff misconduct, a student disciplinary investigation, or concerns around culture and safety, how you respond says everything about who you are. I help you strengthen your organisation through robust investigations and reviews that respect the dignity of everyone involved. I help you conduct investigations and reviews everyone can trust.

Why investigations and reviews matter
I’m Tim Sterne, the investigator and consultant behind Basalt Solutions. Getting your investigation and review processes right has never been more important. You’re now held to much higher standards of accountability for ensuring the physical and psychological safety of your people. Transparent reporting and rigorous investigations and reviews are the expected standard across every sector.
Whether you’re conducting your own investigation or outsourcing to an independent specialist, how you conduct the process directly impacts the wellbeing of your organisation. Unfair processes breed anger, resentment, distrust and unnecessary conflict. On the other hand, when people are consistently given a voice and treated with respect, they are more likely to accept decisions, speak up in the future when things aren’t right, and feel a sense of belonging and commitment to your community.
Experience and expertise
With over a decade of experience in high-stakes investigations, intelligence, and risk management, I focus solely on your investigations and reviews – whether it’s delivering independent workplace and administrative investigations and organisational reviews or developing your internal capabilities. My commitment to my tradecraft means every engagement is conducted with the highest level of professionalism, integrity and attention to detail.
Based in Christchurch, New Zealand, I’m able to provide my investigation and review service remotely or travel to work with clients across New Zealand and Australia.

Organisational Reviews
Sometimes it's not about individual behaviour, it's about systems, processes and culture. A review enables you to understand what happened, why it happened, and what to do next.
