"The sight of a giant All Blacks sign as people fly into Wellington is a really generous and unique way of demonstrating commitment to the team."
Airport chief commercial officer Matt Clarke said the sign was designed for the unprecedented number of international visitors expected to arrive in Wellington in the coming weeks.
"This is an unmissable opportunity to let them know just how excited we are about the tournament and how supportive we are of the All Blacks."
The sign will remain in place for the duration of the tournament, while a competition will give Wellingtonians a chance to share their views on a long term replacement for the 'Wellywood' sign.
