Watch: Soaring Maori waiata echoes around Parliament for new Labour MP Ginny Andersen

A stunning Maori waiata has echoed around Parliament's debating chamber after a maiden speech by Labour MP Ginny Andersen this afternoon.

Ms Andersen had some of her former police colleagues to thank for the moving tribute, as they sang from the gallery in her honour.

Members of Parliament stood spellbound looking up at the performers as the beautiful waiata rang out around the chamber.

House Speaker Trevor Mallard wasn't impressed with the timing though, reminding MPs they needed to include any waiata in the time alloted for their speeches.
