A journalist requested her personal data held by The Warehouse Group (which anyone can do under the Privacy Act). The Warehouse Group is building out the biggest loyalty program in New Zealand. It’s already at 1 million members and has 4 million unique customer identities in its Salesforce stack. It was the first time The Warehouse Group had had to supply this data. The journalist got her own data as well as the data of several other people with the same name (which was a privacy breach according to the Privacy Commissioner).
