New Zealand would back plans to remove Andrew Mountbatten-Windsor from the line of royal succession, a spokesperson for Prime Minister Christopher Luxon has said.

"If the UK Government proposes to remove Andrew Mountbatten-Windsor from the order of succession, New Zealand would support it," the spokesperson said in a statement.

It comes a day after Australian Prime Minister Anthony Albanese said that his government "would agree to any proposal" to remove Andrew from the line of succession over his ties to to paedophile financier Jeffrey Epstein.

Andrew was arrested on suspicion of misconduct in public office on Thursday. He has consistently and strenuously denied any wrongdoing.

The UK government is considering introducing legislation to remove Andrew from the line of succession.
