What we do

Legal investigations and support

File review and compilation of timelines

We can assist legal professionals (or anyone who requires assistance) with case reviews, the creation of accurate timeline(s) and identification of any lines of enquiry and/or further investigative options available.

Witness location, interviewing and evidential statements

We can locate and interview witnesses to assist with any legal matter. We can obtain evidential statements and assist with witnesses at trial if required.

Scene examination

We can provide a thorough scene examination, including detailed sketch(es), photographs and the securing of any exhibits where required. Further forensic analysis of any aspect of exhibits or the scene can be arranged.

CCTV and/or photographic evidence

CCTV and cameras can be used in some circumstances to obtain/ secure evidence. We can provide advice, installation and analysis of data as well as taking care of the wider investigation.

Digital forensics

We live in a digital age and therefore there is often evidence of fraudulent behaviour, deceit, infidelity, cyber- crime, and other misconduct on digital devices. We are able to assist with the identification, analysis and documenting of digital evidence. We also consult with specialists in the field of digital forensics when required.

When digital evidence amounts to the identification of criminal conduct, we will recommend that you report the matter to the Police and we will assist you with this process if required.

Document service

We can locate persons and serve documents for you anywhere in New Zealand and overseas. We provide you with an affidavit/ proof of service.

Workplace Investigations

Reactive investigations

A reactive investigation is usually initiated after an allegation has been made in the workplace or when a significant issue comes to light. This may be an allegation of bullying, sexual harassment, theft or other.

There is huge benefit in using a professional, independent and impartial investigator in these cases. It greatly reduces any risk of perceived bias and criticism that the employer/ company has not responded appropriately. This service ensures a high standard of investigation so you get the best possible outcome. Louise can also provide mediation.

Proactive investigation based reviews/ Corporate reviews

Investigation based reviews involve the independent investigator interviewing a range of employees and assessing the systems and processes in place that are at the core of the business’s functioning.

Typically this process is initiated when more information and clarity is required about the people, systems and processes operating. This clarity enables managers and executive teams to make key decisions that increase productivity and improve workplace culture.

A customised plan is developed after an initial consultation to meet the individual needs of the business.

Workplace risk assessment and security consultation 

This service involves conducting a full risk assessment for your workplace and security consultation.

Gumshoe works with New Zealand’s largest security integrator and we can manage any security related projects for you.

Employee back ground checks

We can provide background checks for you. We will consult with you about the level of information you require and provide you with a report on the individual(s) as requested.

Insurance Services

We provide investigation services for insurance matters. Louise is a member of the Australia and New Zealand Institute of Insurance and Finance (ANZIIF) and focused on further studies to specialise in the insurance industry.


Fraud and Deception

Fraud and deception

Fraudulent and/or deceptive behaviour is often complicated to prove and requires meticulous and in depth investigation. There is a large scale of different types of fraud and deception that can occur. The police are sometimes under-resourced to investigate these matters effectively. Often when someone is being deceptive there is a significant risk to those being deceived, however the situation may not be at a level that warrants Police intervention.

If you are concerned about someone deceiving another (or others) or if you suspect fraudulent behaviour, we can help. It may be a matter that can be resolved privately, or it may be a matter that requires some initial investigation to establish evidence before referring the case to the Police or other agency. Louise is a former Police detective and is able to provide a thorough review of your case and sound advice in regards to best way forward.   

Infidelity/ Domestic matters

Dishonest partners or family members

If you feel that your partner or someone in your life is not being honest with you and you want to find out what is going on, we can help. Whether your partner is having an affair, family member is trying to hide something or there is some other explanation entirely, we can find out and give you the clarity you need.

Internet dating 

If you have met a new person online and you want some peace of mind before taking the relationship further, please contact us. Unfortunately, online and social media dating sites provide a perfect ‘hunting ground’ for some men and women with ulterior motives. These people are often very convincing and good at what they do. We are experienced at investigating these matters and our service may help prevent significant financial loss and emotional harm. 

Missing persons

If you need to locate someone in NZ or overseas, we can help. Each case is very different- in the first instance please contact us with all the information you have in regards to the missing person.

The list of investigation services we can provide is extensive. Please contact us to discuss your matter so we can advise how we can best assist you and what scope of services apply to your situation.
