MPs are said to be well aware of the perception they often waste time, but one of their former colleagues believes they won't do anything about it.
Some eyebrows were raised when after a two week recess, Parliament spent most of the first sitting hour congratulating Kate and William on the birth of Prince Louis and singing a waiata.
Former United Future Leader Peter Dunne told Mike Hosking he once raised the time-wasting issue with the Speaker of the House and party leaders.
"It was yes, nodding heads of agreement, but oh no, we can't do anything about it because people like the opportunity to have their thoughts recorded."
Prime Minister Jacinda Ardern passed a motion this afternoon to congratulate Prince William and Catherine, Duchess of Cambridge on the birth of their third child, Prince Louis.
"Along with many people around the globe, New Zealanders have witnessed and celebrated the joy that the Duke and Duchess of Cambridge have clearly found with their children Prince George and Princess Charlotte," Ardern said.
"I'm very pleased to lead the House's congratulations on the birth of a third child to this close-knit family.
"I'm sure that the duke and duchess are cherishing this special time with their new son, and no doubt Prince George and Princess Charlotte are enjoying getting to know their new little brother."
Ardern spoke about New Zealand's gift to the royal couple – a baby blanket and a selection of New Zealand books.
Leader of the Opposition Simon Bridges said it brought him "heartfelt joy" to congratulate Prince William and Catherine on the birth of their "beautiful bonny boy".
"Can I say to Catherine: it is quite an extraordinary feat, really, to appear publicly only hours after the birth looking so radiant.
"And I'm sure that she, her husband, and the older siblings, George and Charlotte, have real, as I say, joy at the birth of their little one."
Green co-leader Marama Davidson sung a waiata for the couple, which she said she wrote for her own children.
