Independent Workplace Investigations in New Zealand

Karapiti provides independent workplace investigations for New Zealand employers. Steve Lockett, a former NZ Police CIB detective with 30 years’ investigative experience and AWI-CH certification, investigates complaints of bullying, harassment, sexual harassment, discrimination, misconduct and assault, then delivers a clear findings report your decision-makers can rely on. He works NZ-wide, in person or by video.

Independent, Confidential, and Fair

When issues arise in the workplace, an impartial investigation helps protect everyone involved and ensures decisions are made with integrity. Karapiti provides independent workplace investigations for employers across New Zealand.


Each investigation is conducted with fairness, discretion, and professionalism. Whether your business is managing a complex complaint, a staff dispute, or a serious allegation, you can rely on a process that meets legal and ethical standards.

What we investigate:

Our goal is to provide clarity so that you can move forward confidently and in accordance with employment law.

Who I work with

Most of my work is with small and medium-sized businesses. Many come to me through their lawyer, and others contact me directly when a complaint needs to be looked into properly by someone with no connection to the workplace.

Either way, the job is the same: an employee investigation that is fair to everyone involved, follows a clear process, and gives you findings you can rely on when you decide what happens next.

When to bring in an external workplace investigator

Most workplaces can deal with minor issues internally. It’s when a complaint is serious, involves someone senior, or people have already started taking sides that an internal investigation starts to struggle. Whoever runs it is likely to know the people involved, and that alone can make the outcome harder to defend.

An external workplace investigator has no stake in the result. Steve Lockett spent 30 years in NZ Police, 21 of them as a CIB Detective, and is AWI-CH certified. His job is to gather the evidence, hear everyone out and report on what the facts show, so the employer can make a decision they can stand behind.
