Treasures signed by rugby great Jonah Lomu have already started popping up on TradeMe - just hours after the news of his death broke.

The former All Blacks legend died unexpectedly this morning, after suffering from a rare kidney disorder for more than a decade.

It was first reported about 12.40pm.

Coveted items of memorabilia signed by the "gentle giant" started appearing on online store TradeMe, less than two hours after the news.

A signed photo of the star in his heyday has been put online.

The listing references his death straight away: "For sale is a genuine stunning hand signed approximately 8 inch x 6 inch Photo of All Blacks Rugby legend Jonah Lomu who we so sadly lost today."

The description goes on to detail exactly why the photograph is a steal, including highlights of Lomu's career.

"Jonah Lomu was a New Zealand rugby union player," the auction states.

"He had sixty-three caps as an All Black after debuting in 1994. He is generally regarded as the first true global superstar of rugby union. He had a huge impact on the game."

The photo - which has a starting price of $50 - is in good condition with minor marks and bends and "would be a great addition to any collection", the seller states.

The seller says they are a member of the Universal Autograph Collectors Club, so buyers could be certain they were getting the real deal.

The photo will come with a lifetime authenticity certificate, the seller states.

Another item, a Jonah Lomu photo trading card signed by the star, has also been listed by the same user.

It is going for a whopping $300.

A copy of the documentary "Anger Within: Jonah Lomu - A Rugby Legend" has also been put on TradeMe since Lomu's death.

It includes a synopsis of the film, stating: "Jonah Lomu is without a doubt the most famous rugby player of all time. His physique, his power, his speed and his determination revolutionised the game."
