What does a private investigator do?

Our private investigation services
Surveillance
Discreet, professional surveillance for personal, legal, or insurance matters. We monitor subjects and produce documented photographic or video evidence that holds up to scrutiny.
Tracing
Need to locate a person? We use discreet enquiries and established contacts to trace individuals across Hamilton, Waikato, and New Zealand-wide — with impressive success rates.
Insurance investigations
We work with insurers to investigate potentially fraudulent claims. Documented evidence of fraudulent activity is gathered professionally and prepared for legal use.
General enquiries
Sometimes a discreet door knock or targeted enquiry is all that's needed. We handle general investigation requests with the same professionalism as larger cases.
Areas we cover
Hamilton & Waikato region
Based in Hamilton, we cover the full Waikato region including Cambridge, Te Awamutu, Morrinsville, Matamata, Te Aroha, Huntly, Ngaruawahia, Te Kowhai, Raglan, and Otorohanga. Travel to the Coromandel can also be arranged.
For cases beyond Waikato, Stephen's nationwide network of trusted agents means we can assist anywhere in New Zealand. If you need a private investigator in NZ — not just Hamilton — we can help.
Frequently asked questions
Is hiring a private investigator legal in New Zealand?
Can surveillance evidence be used in court?
Yes. Private investigators operate legally in NZ. All work carried out by West Document & Investigation Services is conducted within New Zealand law. We never engage in activities that would breach privacy legislation or constitute harassment.
Yes, provided it was gathered lawfully. Stephen's 24-year police background means all evidence is documented in a way that meets legal standards and can be presented in court proceedings if required.
Do you only cover Hamilton, or can you work NZ-wide?
Both. Stephen is based in Hamilton and covers the Waikato region directly. For investigations outside Waikato, we work with a network of trusted agents across New Zealand to ensure your matter is handled locally and professionally.
How do I get started?
Simply call or send an enquiry. Stephen will discuss your situation confidentially and advise on the best approach. There's no obligation to proceed.
