Emotional Eden Park Memorial for All Black Legend Jonah Lomu

A Maori mourning chant echoed around New Zealand's spiritual home of rugby on Monday as New Zealand paid tribute to All Black great Jonah Lomu with thousands of fans packing a memorial service at Auckland's Eden Park.(New Zealand Pacific Community Bids Farewell)

Former All Blacks including Michael Jones and Frank Bunce carried a black casket containing his body onto the field as Lomu's wife Nadene and sons Brayley, 6, and Dhyreille, 5, wearing black shirts with the winger's number 11, followed with heads bowed.

Lomu died unexpectedly at his Auckland home this month aged just 40 from cardiac arrest related to the chronic kidney disease that cut short his playing career.

The memorial ceremony was broadcast live by all major television stations in New Zealand, where Lomu was a beloved figure even among those too young to have seen him in action.

Eden Park was a happy hunting ground for the player, who appeared in six Tests at the venue and won five of them.

Former All Blacks coach John Hart said there could be no better place to say farewell to the legend.

"We've chosen Eden Park because it's the spiritual home of rugby and somewhere that Jonah loved so much," he said.

"Jonah, you were a freak on the field and a gentle, caring giant off it."

World Rugby chairman Bernard Lapasset made the 18,000 kilometre (11,000 mile) trip from France to pay his respects to a man he said helped bring the sport into the professional era.

"He's an icon in rugby and I have to represent all the fans that Jonah had in the world," he said.

"This fantastic man delivered a very great message about rugby to the world... he terrified defences and thrilled spectators with a brand of running rugby that had never been seen before."

Since Lomu's death, tributes have poured in from across the rugby world, with many current players recalling how he inspired them to take up the game.

Such was his fame that condolences also came from beyond the sport, including Britain's Queen Elizabeth II, British footballer David Beckham, Hollywood star Morgan Freeman and singer Elton John.

Former Wallaby Tim Horan said no player in the sport had ever matched Lomu's worldwide appeal.

"He put rugby on the map globally. He helped put rugby on the map in areas were people don't normally watch it," he said.

Lomu scored 37 tries in his 63 Tests for New Zealand, becoming rugby's first global superstar with a combination of raw speed and brute strength.

But Prime Minister John Key said it was a bitter defeat that showed Lomu's true character, recalling his sportsmanship when the All Blacks suffered a shock loss to France in the semi-final of the 1999 World Cup.

"Despite his deep disappointment, Jonah remained on the field until he'd shaken the hand of every single French player," Key said in a video address from Paris where he is attending climate talks.

"More often than not, he was also the last player standing on the sideline signing autographs for young fans. That was Jonah."

Former sevens teammate Eric Rush joked about Lomu's prodigious appetite and dislike of training, his voice faltering as he remembered his friend.

"We're going to miss you big man, rest in peace brother," he said.

The memorial service will be followed by a private funeral on Tuesday.
