Around 30 scouts at a jamboree in Hamilton have come down with Covid-19.

Te Whatu Ora says the numbers are a small proportion of the 4000 scouts who had assembled for the jamboree.

A spokesperson for Te Whatu Ora - Health New Zealand Waikato says the Covid cases have been reported to the Medical Officer of Health.

"It was established the jamboree's medical team on site were following established protocols and were confident they were able to manage the positive Covid-19 case load.

"With today being the last day of the event, participants were reminded of the importance of isolating, travelling home via the most direct route and remaining masked for the duration of their journey home."

The 23rd Aotearoa New Zealand Scout Jamboree is being held at Mystery Creek.

The jamborees are usually held every three years but the last one was disrupted by the pandemic.
