Harassment often becomes harder to explain because it happens in fragments: a message late at night, an unwanted appearance at work, a withheld number, a comment made where nobody else can hear it. To record harassment evidence effectively, turn those fragments into a clear, accurate record without placing yourself at further risk or compromising the material you may later need.
For people facing stalking, abuse, intimidation, workplace harassment or persistent unwanted contact, the priority is safety. Evidence matters, but no photograph, message or recording is worth confronting someone, meeting them alone or delaying a call for help. If there is immediate danger in New Zealand, call 111.
Start a harassment evidence record immediately
The strongest records are usually made close to the event. Memory fades, small details become uncertain and a pattern can be difficult to establish after weeks or months have passed. Begin a factual incident log as soon as you can, using a notebook, document or secure notes application that you can access consistently.
For each incident, record the date, approximate time, location, who was involved, what happened and how it affected you. Write what was said as accurately as possible, using quotation marks only for words you are confident were used. If you are unsure, say so. A note such as, “I believe he said he would come to my address”, is more credible than presenting an uncertain recollection as an exact quote.
Include the names and contact details of witnesses where appropriate. Also note practical details that may later matter: the vehicle registration, a description of clothing, the direction someone travelled, the platform used for a message, or whether there may be CCTV nearby. Do not embellish the account. A calm, chronological record is far more useful than a detailed account that mixes fact, assumption and hindsight.
It is also sensible to record what you did next, such as notifying a manager, contacting Police, blocking an account, changing a routine or telling a family member. This can help demonstrate both the impact of the conduct and the steps you took to protect yourself.
Preserve original material, not just screenshots
Screenshots are useful, but they are rarely the whole story. They may not show the sender’s account details, the date and time, the wider conversation or whether content has been edited. Keep the original messages, emails, voicemails, social media posts and call logs wherever possible.
Save material in a secure place and retain the original device or account access if it is safe to do so. Back up copies to a protected storage location that the other person cannot access. If you share a device, email address or cloud account with the person involved, use caution. Changing passwords, enabling multi-factor authentication and creating a separate secure account may be necessary, but consider whether sudden changes could increase your immediate risk.
When taking screenshots, capture the surrounding context. This may include the account name, profile image, date, time, URL or platform information, and prior or subsequent messages that explain the exchange. For emails, preserve the complete email rather than forwarding only the text. Keep attachments in their original form.
Avoid editing files, adding annotations directly over an image or repeatedly re-saving video. Make a working copy if you need to highlight something for your own reference, while retaining the original untouched. A simple file name that includes the date and a short description can make a large collection manageable, for example: “2026-08-14_2140_unwanted-text-message”.
Use recording tools carefully and lawfully
Audio or video can be compelling, but it can also create legal, privacy and safety issues. The rules around recording conversations depend on the circumstances, the people involved and how the recording may be used. Before making a covert recording or placing any recording device, obtain legal advice relevant to your situation.
Never enter private property, install equipment where you have no right to do so, access another person’s accounts, or use tracking software or devices without lawful authority. Material obtained improperly may create serious problems and can put you at greater risk.
If an incident occurs in a public place and it is safe to do so, a contemporaneous photo or video may assist with identifying a person, vehicle or location. Keep your distance. Do not announce that you are recording, argue with the person or remain nearby to obtain better footage. Leave and seek assistance if the situation feels unsafe.
CCTV can be valuable, particularly after an incident at a workplace, retail premises, apartment building or car park. Footage may be overwritten quickly, so make a note of the camera location and the relevant time period. Notify the property owner, manager, Police or your legal representative promptly. Do not assume footage will be retained indefinitely.
Build a timeline that shows the pattern
A single unpleasant interaction may be explained away. Repeated unwanted contact, surveillance, threats, intimidation or interference can look very different when each event is placed in order. Your timeline should make that sequence easy for another person to understand.
Create one entry per incident and attach or reference the supporting material. For example, an entry may identify a text-message screenshot, a voicemail file, a witness statement and an incident report number. Keep the entry factual and concise. The purpose is not to tell the whole story every time, but to show what happened, when it happened and what evidence supports it.
This approach is especially useful where harassment crosses channels. A person may send messages, contact colleagues, appear at your home, create false online profiles or make complaints designed to cause reputational damage. A consolidated timeline can show the connection between conduct that otherwise appears unrelated.
For workplace matters, retain relevant policies, emails to management, meeting notes, roster information and any formal complaint correspondence. Follow internal reporting processes where it is safe and appropriate. If the person is a client, supplier or member of the public, tell your employer about any safety concerns rather than trying to manage the situation alone.
Keep evidence secure and protect your privacy
Evidence can be sensitive. It may contain your address, workplace, children’s details, private communications or information about other people. Limit who receives copies and avoid posting material publicly or sending it to friends for reassurance. Public sharing can escalate a situation and may affect later action.
Maintain a simple record of who has received material, what was sent and when. If you provide evidence to Police, a lawyer, insurer, employer or investigator, keep a copy of the covering email or acknowledgement. This helps preserve a clear chain of handling, particularly where files are later reviewed in a formal process.
Do not delete abusive messages simply because they are distressing. Instead, store them away from your everyday view. If you need emotional support, ask a trusted person to help organise the material, provided they understand the need to preserve it exactly as received.
When professional assistance may be warranted
Professional assistance can be appropriate where the harassment is persistent, the identity of the person is uncertain, there are concerns about personal safety, or the matter may proceed to court, employment action or an insurance investigation. An experienced investigator can assess available information, identify lawful avenues for enquiries and produce clear, objective reporting.
The Neill Group works discreetly with private individuals, legal professionals, businesses and government clients throughout New Zealand on sensitive investigative and risk matters. Any investigation should be lawful, proportionate and focused on obtaining reliable information rather than escalating conflict.
A professional can also help distinguish useful evidence from material that is unlikely to assist. That matters when you are overwhelmed by hundreds of messages, repeated incidents or conflicting accounts. Careful organisation can reduce stress while ensuring significant events are not lost.
The most useful evidence is usually not dramatic. It is accurate, preserved promptly and supported by a consistent timeline. Start with what you know, keep yourself safe, and allow the record to speak clearly when it is needed.
