The Unexpected Impact of DNA Ancestry Tests

DNA surprises in New Zealand are becoming increasingly common as more people take direct-to-consumer ancestry tests. These tests can uncover life-changing discoveries – such as learning that the person you believed to be your parent is not your biological parent.

This type of revelation is often referred to as a “Not Parent Expected” (NPE) event, and it can have a profound impact on mental health, identity, and family relationships.

Research has shown that many people who receive unexpected DNA results experience significant emotional upheaval. These discoveries may lead to a reassessment of personal history and even a fundamental shift in identity.

Common reactions include:

• shock and confusion

• grief and a sense of loss

• feelings of betrayal or mistrust

• strain in family relationships

For some, the discovery can feel destabilising, especially when parents or family members withheld the truth.

Not All DNA Surprises Are Negative

While NPE events can be distressing, not every story is painful. For some people, learning the truth can bring clarity, healing, and even a sense of belonging.

Positive experiences may include:

• forming new relationships with biological parents or siblings

• embracing new cultural or ancestral roots

• relief at knowing their genetics don’t define their upbringing, particularly if their relationship with the assumed parent was difficult

In these cases, DNA testing provides validation and opens new opportunities for connection.

The Importance of Support

Whether the outcome is painful, positive, or somewhere in between, having support is vital. Many people turn to friends, family, counsellors, or peer support groups to help them process the experience.

In New Zealand, support can be found through organisations such as:

• Adoption NZ – offers peer-led support and connects people impacted by adoption, fostering understanding, advocacy, and compassionate connection.
• Mental Health Foundation of New Zealand – a charity offering wellbeing tools, information, and links to support services across Aotearoa.
• NZ Society of Genealogists (NZSG) – offers education and resources on DNA testing, emphasising the importance of being prepared for unexpected results and understanding what DNA testing can and cannot tell you.

These services, along with online peer groups and forums, can offer connection, understanding, and reassurance from people who have navigated similar discoveries.
