You are in England & Wales and the person doing this is in New Zealand. You report at home, and at the same time trigger action where they actually are.
999 (call and ask for the police if you or someone else is in immediate danger or a crime is in progress). 112 also connects to the same emergency operator across the EU/UK.
Most people here are not in an active emergency. To start an official record, use the non-emergency steps below.
Keep doing everything below in England & Wales. At the same time, the fastest leverage often sits in New Zealand, where the person actually is.
The fastest practical lever against a perpetrator located in New Zealand is the Harmful Digital Communications Act 2015 civil route: complain to Netsafe (the Approved Agency, https://netsafe.org.nz/report, 0508 638 723), and if it cannot resolve the matter, use Netsafe's written summary to apply to the District Court for an HDCA order (takedown, cease publication, correction, right of reply, or identity disclosure). For serious threats or criminal conduct, NZ Police can act under the Crimes Act / HDCA s 22 directly because the offender is locally located and within jurisdiction. NOTE: where the poster is offshore the HDCA's real limit is service-of-process (no statutory provision for serving an overseas defendant; leave of the District Court under District Court Rules Part 6 is required); that limit does not bite when the perpetrator is in New Zealand.
When the perpetrator is in New Zealand and the victim is overseas, the foreign victim should report through their OWN local/national police, who relay the matter police-to-police to INTERPOL Wellington (the NZ National Central Bureau hosted at Police National Headquarters). Neither the public nor a foreign victim can contact INTERPOL or the NCB directly: 'INTERPOL NCBs do not respond to requests from the general public... contact their local or national police, who will in turn contact the NCB.' NZ Police can also be reported to directly via 105 (https://105.police.govt.nz) for the criminal record. For evidence held in or action needed in New Zealand, the foreign authority uses a Mutual Legal Assistance (MLAT) request handled under New Zealand's Mutual Assistance in Criminal Matters Act 1992 via the Crown central authority. New Zealand is also a Party to the Budapest Convention on Cybercrime (in force for NZ 1 December 2025), which provides additional cross-border cooperation channels for electronic evidence. An FBI Legal Attache now operates a standalone office in Wellington (opened 31 July 2025) for liaison with US authorities.
Because the perpetrator is locally located, NZ Police and the District Court can act without the cross-border MLAT or INTERPOL delays that slow cases where the offender is abroad. If Netsafe’s role changes, NZ Police on 105 is the fallback intake.
File a non-emergency report, and do the single most important thing: get your report / reference / occurrence number. That number is the key that unlocks platforms, prosecutors, employers and protective orders.
Use the online report form for non-emergency stalking, harassment, threats, defamatory/abusive content. For stalking/harassment many forces use a dedicated 'Report online' button that triages you to the right form. CRITICAL for a paper trail: at the end of the report ASK FOR and record the crime reference number / occurrence / log number; the report is handled by the control room the same as if you spoke to an officer. Keep screenshots and evidence.
Call 101 to report a non-emergency crime or get advice and to generate an official log. Ask for a crime/incident reference number. Also the route for Scotland fraud reporting (Police Scotland).
Anonymous reporting if you do not want to give your details. NOTE: This does NOT create a victim crime report or give YOU a personal crime reference number, so it is not the channel for starting your own official paper trail; use 101 or local-force online report for that.
Use for fraud, online extortion/sextortion demanding money, identity fraud/identity theft, and cyber-dependent crime. Generates a reference number for your paper trail. Covers England, Wales and Northern Ireland; Scotland callers report to Police Scotland on 101. Report Fraud went live 4 December 2025 with Action Fraud traffic redirecting and a full public launch in January 2026.
File here in addition to, not instead of, your local police report.
INTAKE + TRIAGE + INTELLIGENCE, generally NOT a direct investigator of individual reports. National reporting front door for fraud and cyber-crime (replaced Action Fraud; full public launch January 2026, redirects began 4 Dec 2025). Reports are assessed by the Report Fraud National Crime Analysis Service (N-CAS) and disseminated to local forces or specialist units; serious/complex cases are flagged for investigation. A victim support service is provided. Phone unchanged from Action Fraud (0300 123 2040).
Investigates the most serious and organised cyber-crime; leads, supports and coordinates the UK response to serious/organised crime including cybercrime and economic crime that crosses borders. The public does NOT report routine cybercrime directly to the NCA - the NCA directs victims to local police (101/999) or Report Fraud; it acts on intelligence and serious-organised-crime cases, not individual intake.
INTAKE + TECHNICAL TAKEDOWN, not a criminal investigator of harassment. Receives reports of scam/phishing emails, texts and websites; can investigate and remove malicious sites and shares intelligence with the NCA and City of London Police. Not the channel for harassment/threats/doxxing - it is for scam/phishing infrastructure.
PLATFORM REGULATOR, NOT an individual-complaint body and does NOT investigate your specific case or give you a personal remedy. Regulates social-media and search platforms' duties to remove illegal content (including harassment, threats, intimate-image abuse). Can fine platforms up to 10% of qualifying worldwide revenue (or 18 million pounds, whichever is greater) and, in extreme cases, seek court orders to block a service. Victims still report the crime to police; Ofcom handles systemic platform compliance. Illegal-content duties live since 17 March 2025.
