Wellington fans line up to see All Blacks

All Blacks captain Richie McCaw told huge crowds gathered to salute the team in Wellington they couldn't have won the World Cup without them.

Thousands of supporters are lining streets in the city centre to get a glimpse of their heroes as they complete their third and final victory parade this lunchtime.

The parade began in Civic Square about 12.25pm after Wellington Mayor Celia Wade-Brown told the "mighty All Blacks'' they had lifted the gloom after a tough year blighted by the Pike River disaster and Christchuch earthquakes.

She thanked staff and volunteers who helped make the tournament a huge success before McCaw addressed the crowd.

He said his side couldn't have won the Webb Ellis trophy without the support they had from throughout the country.

The squad split into groups to climb onto several floats before their journey along Willis Street and Lambton Quay to Parliament.

Blustery, drizzly weather didn't deter the thousands lined up on Lambton Quay to see the team.

Sandra Bednarek, dressed in an All Blacks flag and a "Keep Calm, Piri's on'' t-shirt, said she and her kids wouldn't be put off by the rain.

"We're hoping ... that it just stays like this,'' she said.

People found vantage points on roofs and were watching from office buildings and multistorey car parks.

Two teenagers were perched in a tree halfway along the capital's main shopping street.

Cheers erupted sporadically and fans took part in a Mexican wave.

Nadene Mackey had a rugby bal signed by Israel Dagg and said she was "stoked'' and that it would become a family heirloom.

Victoria University commerce students Angelka Vegar and Kate Dogan had been staking out a spot since 10am carrying signs for their heart-throbs, one of which read: "Kieran Read this sign.''

Ms Vegar said she loved all the players but they had made the signs for their favourites.

"They're just great players. Israel Dagg is single ... we want them to come over and talk to us.''

On the prospects of a kiss from one of the players, Ms Vegar said: "You never know.''

Adam Rikihana said he had been waiting 24 years for this.

He was keen to see all 30 in the squad but McCaw especially.

If he got the chance to speak with McCaw, he'd say: "Kia ora man, well done.''

Rebecca Griffiths and her four children were also looking forward to seeing the team.

"We're all very proud of them. It's great _ it's what we all wanted.''
