If required, we can utilise a covert female operative to test the commitment of your partner, we refer to this test as a ‘honey trap’, this is a covert ‘peace of mind’ operation.

Child & Youth Investigations 

We use recognised best practice for surveillance to determine what happens when a parent or caregiver is with their child. We document any signs of abuse or neglect that is observed and gather evidence that may prove a child is being abused.

We can confirm if a parent or caregiver engages in criminal activity, neglect, or other activities that would directly affect a child’s welfare. Based on the evidence gathered, parents and the courts can determine what to do to ensure the child’s safety.

In a court room, a private investigators findings provide more credence than a parents accusations especially against a former partner. If you have any suspicions of abuse or foul play, employing a licensed private investigator is essential.

Insurance Investigations 

In the 1980’s, Dion was one of the first licensed private investigators in New Zealand to carry out investigation assignments for the Accident Compensation Corporation (ACC). Dion works closely with a number of major private insurance company’s within New Zealand and worldwide to confirm the validity of injury and disability related insurance claims.

Injury and disability insurance claims can amount to substantial sums which sometimes require validation prior to any compensation or payment to ensure the correct entitlement. Dion carries out a range of insurance related investigation activities including factual inquiries, claimant interviews and surveillance.

Fraud & Theft Investigations

Dion has decades of experience detecting and investigating fraud and theft for New Zealand business, government agencies and private individuals. Fraud is a worldwide concern with an estimated cost to New Zealand business and government agencies estimated at $6 billion a year. Fraud occurs in any business no matter its size or stature.

Fraud inside a business or organisation frequently occurs through poor internal controls and processes, this allows a window of opportunity for people in positions of trust and responsibility to carry out offending such as theft or fraud. We know fraud can damage a company or organisations reputation, brand and culture.

Finding the individuals responsible for a theft is only the first step; putting in place the remedial processes and policies following the incident is our ongoing commitment to protecting your long term interests. We can help you to respond professionally and with an independent perspective.

Alcohol, Drug & Substance Abuse Investigations 

Do you suspect your family member, partner or employee maybe using excessive alcohol, drugs or illegal substances? Did you know that if drugs are used on your property, you can also be prosecuted for their criminal activity?

Alcohol and drug abuse is known to be the source of criminal activity and anti-social behaviour, alcohol, drug and illegal substance investigations will help to provide the answers you are seeking.

Psychological & Physical Abuse Investigations 

Is someone in your life a possible victim of physical or psychological abuse?

Private investigators can provide evidence to help protect you and your loved ones. The factual evidence provided by licensed private investigators are often used for the basis of a complaint to police or for legal purposes.

Covert Surveillance 

It is important for everyone to understand that surveillance is both legal and ethical. Dion and his associates will only conduct surveillance for a legitimate purpose and in a legal manner. Surveillance is a powerful tool used in investigations where evidence is obtained in order to secure prosecutions – substantial intelligence is often gained from these operations.

The current measures of surveillance and intelligence gathering include insurance claimant surveillance, domestic related surveillance and surveillance for theft or fraud related investigations.

Dion and his team of nationwide licensed private investigators possess significant expertise in the area of photographic and video surveillance. All surveillance and investigation activities are carried out to the highest level of ethical and professional standards.

Technical Surveillance Counter Measures (TSCM)

Our contracted specialist can detect hidden cameras and listening devices often referred to as “bugs”. Our specialist can locate hidden cameras, tracking devices and spyware.

The law forbids the use of hidden cameras and recording devices without an individuals consent. It is a clear breach of privacy when an individual places surveillance on another individual without their consent.

People install hidden cameras and listening devices for a variety of reasons, in some cases to gather evidence of a cheating partner or to gather sensitive personal information, competitors secrets, business plans, designs or financial information.

If you have any concerns in this area, we will refer to our preferred specialist for assistance.

Formal Interviewing

Formal interviews can be conducted to support civil, criminal or personal investigations. Our interview process includes the format used by the police and other law enforcement agencies based on PEACE, cognitive and the Reid interview techniques.

Interviews can be recorded if requested and consent is obtained by the parties involved.

Audits & Reviews 

The Neill Group conducts nationwide mystery customer programmes designed for the commercial and retail sectors. We covertly audit the communication, compliance and integrity of your customer services people.

Covert visits to your business are known to uncover potential areas of loss and identify risk to your business.


We have a forensic expert available to investigate a wide range of cyber-crimes including online fraud, stalking and harassment. Our I.T. forensic expert we can assist with revealing the true identity of anonymous blogs, fake websites, Facebook profiles, email communication, website ownership, IP addresses and the forensic recovery of information.

Loss Prevention

The handling of product and stock – both in retail and distribution – generally operates with an acceptable shrinkage percentage to allow for losses incurred through internal and external factors such as damage, breakages, faults and theft.

Often, many of these losses are caused by data entry or coding errors, and can be reduced through the introduction of improved internal processes. Once stock is accurately accounted for, the true extent of fraud or theft can be established.

We have worked with a number of national clients to provide security and loss-prevention services across diverse industry sectors.

Hidden Cameras 

Modern technology has allowed hidden cameras to almost be undetectable. Our contracted technical surveillance expert uses covert (hidden) cameras to detect criminal offending and provide evidence in criminal matters.

Hidden cameras provide quality footage to expose what is happening inside your business or your home.

Undercover Operations

We have access to a highly trained undercover agent who has many years of experience within the intelligence field. Our agents is commonly used inside a business premises to detect theft, fraud, unexplained loss and to prove criminal offending.

Undercover operations successfully reveal activities including the use of alcohol, drugs and in some cases, workplace bullying. Our undercover agent supports our investigators to gather evidence that can be used for a criminal prosecution or to assist with civil litigation.

Criminal Defence Assignments 

While all criminal cases do not require the services of a licensed private investigator, in cases that do, the use of a licensed private investigator often becomes one of the most important members of the legal defence team. A licensed private investigator employed by the defence team performs specific tasks in order to prepare an effective defence against criminal charges.

A private investigator will review the police investigation and if required, interview witnesses to discover if there are changes in their statements and to establish any new leads of inquiry.

Investigations are carried out in accordance with legal requirements and based on recognised best practice.

Background Checks

Thanks to modern technology, a discreet background check allows us to find out about someone quickly before we give them the opportunity to be in a position of trust or to potentially harm us. A comprehensive background check will reveal a person’s driving record, credit history, education and with their consent, criminal history.

Employers routinely carry out background checks and screen prospective employees, you should do the same in your business and personal life. If you have any doubts or concerns, before you make a personal or business commitment, consider a discreet background check by a licensed private investigator.

While some people believe it’s easy to search a person’s name on the internet to find out more about them, that is simply not enough. If you are in doubt or have a suspicion, contact a licensed private investigator who will provide the facts and reveal the truth.

Methamphetamine Testing 

We call on an expert methamphetamine testing agency to assist us in detecting methamphetamine (meth), commonly referred to as ‘P’.

Our associates provide mobile independent methamphetamine testing in the greater Wellington region and throughout New Zealand for real estate agents, landlords, commercial property owners, vehicle rental companies or private individuals who need positive assurance their property has not been used for the manufacture of methamphetamine.

Identity Verification

Internet or online dating has changed the way people meet, no longer are face to face meetings necessary to kindle a relationship. What happens if the person behind the computer screen is not the person they say they are?

Online dating scams and internet based fraud is now very common and rapidly growing, anyone can be targeted. Are you looking for a relationship online?

A search to connect with someone for a relationship can make you vulnerable and as a result, these emotions are often used by offenders to access your private life including your bank account, assets and personal property.

Pre-Employment Screening

High staff turnover, unsuitable employees and dishonest staff can ultimately cost your company or organisation thousands of dollars in time, money and resources. That’s why it’s important you recruit the right person from the very beginning.

Skip Tracing

Attempting to locate birth parents, siblings, debtors, witnesses or defendant? We will assist you to find the missing pieces – we know the internet is a useful tool for locating people, but, it often provides incorrect or historic information, employing a private investigator will often open new avenues of inquiry that may lead to a positive result.

We work closely with law firms, enforcement agencies, financial institutions and private individuals who are seeking to locate a person of interest. We provide a professional tracing service that utilises proven information sources, confidential informants and effective tracing tools to assist in tracing anyone within New Zealand or worldwide.
