The outbreak of food-poisoning at Eden Park is estimated to have cost nearly $72,000.

The Auckland Regional Public Health Service has released its report into the Norovirus outbreak following the All Blacks - Ireland match on June 17.

The report has found the worst hit were those in the "Hall of Legends".

It says those who became sick were 32 times more likely to have eaten the contaminated Korean oysters. The report says the oysters were served raw, despite packaging stating the oysters should be cooked.

Recommendations have been made to the caterer and the Food Safety Authority in relation to managing public health risks of Korean oysters.
