A former National MP has revealed details of being targeted by Chinese state-sponsored hackers in 2021.

Simon O'Connor and former Labour MP Louisa Wall claim they were specifically hit in the cyber-attack, revealed last month.

Both say they weren't informed by the current or previous Government - and want an investigation.

Both represented New Zealand on the Inter-Parliamentary Alliance on China.

O'Connor says the hackers sent a dodgy pixel in an emailed image.

"If we'd opened it, it would have sent information such as what browser we'd been using, what's our IP address - and that's then sort of the first steps for a further attempt to be made to extricate more information from our systems."
