The 2.3km walk - previously 4.5km - travels along Ponsonby Rd before turning right on Great North Rd and then down Bond St and towards the stadium.
Part of the change was due to the construction happening at the waterfront, but organisers - Auckland Tourism, Events and Economic Development (ATEED) - also wanted fans to make the most of bars and restaurants on Ponsonby Rd and Karangahape Rd along the way.
Other en-route entertainment included DJs, the Auckland Gospel Choir, barbershop singers, Highly Flammable light dancers and other street performers.
Street artists would also create murals at Western Park, Bond St and Walters Rd which fans could use as backdrops for photos. They featured both New Zealand and Australian themes.
Flay said a surprising number of Wallabies fans had been stopping to have a picture with the Australian mural.
"It's amazing how many Wallaby fans have come over and they've loved being able to get their photo taken with the wall," she said.
The Fan Trail was first created for the 2011 Rugby World Cup, partly to reduce congestion on the city's roads, and to provide entertainment before the games.
It was so much of a success, it has become a fixture for Eden Park tests.
A sold-out crowd is expected for tonight's match, the second of three in the series.
Prime Minister Jacinda Ardern is among the thousands of fans who have turned out to watch the world champion Black Ferns - who made it two in a row against Australia tonight - ahead of the All Blacks clash.
Most of the talk in the lead up to the All Blacks test has been about the Wallabies' Eden Park hoodoo – they haven't won at Eden Park since 1986, and haven't won on New Zealand soil since 2001.
But the All Blacks will still be wary as they only need to look back to last year to see what a wounded Wallabies side can do, when they rushed out to a 17-0 lead over the All Blacks in Dunedin after being thumped in Sydney the previous week. (However, the Wallabies still ended up losing that game in the final moments.)
