MediaWorks (mediaworks.co.nz) suffered a data breach in 2023 that exposed around 162,710 accounts. If you had an account, some of your personal data may be circulating in leaked databases. The fastest way to know is to check your own email — free, in about 30 seconds, no password required.
What happened
In March 2024, millions of rows of data from the New Zealand media company MediaWorks was publicly posted to a popular hacking forum. The incident exposed 163k unique email addresses provided by visitors who filled out online competitions and included names, physical addresses, phone numbers, dates of birth, genders and the responses to questions in the competition. Some victims of the breach subsequently received ransom demands requesting payment to have their data deleted.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the MediaWorks breach exposed and what each item actually enables:
Home addresses feed people-search and data-broker sites, which republish them publicly. They also make phishing far more convincing and, in the worst cases, enable real-world harassment.
Date of birth is a permanent identifier used to verify identity by phone. Combined with a name and address it is often enough to impersonate you.
Enables SIM-swap attacks (hijacking your number to intercept SMS codes), smishing, and voice scams that appear to come from your bank.
Puts you on spam and phishing lists, and confirms to attackers that you hold an account with this service — which makes impersonation emails more believable.
Also listed in this breach: Dates of birth, Email addresses, Genders, Phone numbers, Physical addresses.
What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Home addresses: Get your address removed from data brokers — they re-list roughly every four months, so this needs repeating.
- Dates of birth: Never confirm your date of birth to an inbound caller — hang up and dial the organisation back on a published number.
- Phone numbers: Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider.
- Email addresses: Treat any message referencing this service with suspicion, and never act on links in unexpected emails.
- Check whether your own email appears in this breach — run a free scan to confirm before you spend time on the steps above.
This breach put your details on data-broker sites
Because MediaWorks exposed home addresses, this is one of the breaches that feeds people-search and data-broker sites. Those sites scrape leaked databases, combine them with public records, and republish the result as a searchable profile — which is how a single breach turns into a permanent public listing. Removal works, but brokers typically re-list within about four months, so it has to be repeated.

How urgent is this now?
This data has been circulating for around 3 years, which means it has been copied, combined with other leaks and indexed by search tools many times over.
Remember: a breach can't be "un-leaked" — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can't, and remove what has been republished.
