The minister responsible for the spy agencies' has asked officials for a please explain, after two former MPs claimed they were never informed they were victims of a China-backed cyber attack.
Louisa Wall and Simon O'Connor, both former members of the Inter-Parliamentary Alliance on China, claimed to have been specifically targeted in 2021, the New Zealand Herald reported.
It is unclear if their claims are linked to China's hack of New Zealand's Parliament three years ago.
The former MPs have alleged the United States Federal Bureau of Investigation told the New Zealand government in 2022 they had been targeted, but that information was never passed on to them.
It is also unclear which government agency may have received that information from the FBI.
Wall and O'Connor said they learned they had been targeted through the Inter-Parliamentary Alliance on China, not through the New Zealand government.
The minister responsible for the Government Communications Security Bureau (GCSB) Judith Collins has asked the agency for more information.
"We'll find out the facts and I've certainly asked for an explanation and just to get the facts myself."
Prime Minister Christopher Luxon said he had not been briefed on the matter.
But he added if MPs had been hacked, it was his expectation they would be informed of that.
