Do you need to uncover abuse, fraud, theft, harassment or relationship dishonesty? Our Wellington investigation experts are discreet, effective and highly experienced.

According to research, more than 25% of adults in New Zealand have cheated on their partners, and approximately 15% have had a long-term affair. Stop guessing, we are to get the facts and uncover the truth. Infidelity in a partner is a troublesome matter to confront on your own, but with the help of our trained and qualified private investigators, you may gather the facts with confidence and begin the healing process.

Our expertise and experience, as well as absence of emotional involvement, allows for efficient information gathering. We know that many people who attempt to catch their cheating spouse or partner by themselves struggle to know what to look for or feel too agitated as the process develops. Our clients have told us that months of their life were squandered trying to figure out if their spouse or partner is cheating – but could not do so because of poor investigation skills and lack of equipment.

As independent private investigators, you can be rest assured there will be no emotional attachments in our investigation process. Leave it to the professionals, hire a licensed private investigator, we investigate without emotional attachments.
