NZ First leader Winston Peters will be out of Parliament for the rest of the week.
Making the announcement on Monday during her post-Cabinet press conference, Prime Minister Jacinda Ardern said the NZ First leader is suffering from what she believes is an old rugby injury.
"The deputy Prime Minister attended Cabinet today but will not be attending Parliament for the remainder of this week," Ardern explained.
"He's having a small surgical procedure to address an old leg issue and has been advised post-procedure to have some days avoiding travel and not bearing weight.
"We wish him well and look forward to his quick return in due course."
Peters, 74, is a former New Zealand Māori rugby representative and captain of the Auckland Māori Rugby team.
