Every seat at Eden Park will have a red nose attached to it tomorrow night when the All Blacks team up with charity Cure Kids for their test match against Australia.

The All Blacks and Cure Kids hope to see the sold-out crowd all don their allocated red nose at half time with the goal of getting 50,000 people to sport the look including spectators, support staff and media.

"It will be interesting," All Blacks captain Richie McCaw said. "It will be cool."

McCaw said visiting sick children was a rewarding experience for the players.

"Where the All Blacks are held in this country, we are lucky we get the opportunity to put some smiles on some faces," he said. "It brings into reality on what we do. We just play sport but some of the challenges these kids have ... just to see a smile is a pretty cool thing to do."

The red nose handout is part of a big day for the charity who will also run a four-hour family-focused event at The Cloud in Auckland with the Webb Ellis Cup and Bledisloe Cup both on display.

Auckland Tourism Events & Economic Development has also re-introduced the World Cup fan trail for the test.

The trail from Auckland's waterfront will operate, irrespective of weather conditions, and feature a range of activities along the 4.5km route from Queen Elizabeth Square from 4pm onwards and end at Eden Park.

The trail will be officially opened by Auckland mayor Mayor Len Brown and a member of the All Blacks who will accompany the Bledisloe Cup from the Cloud to the start of the fan trail about 4.30pm.
