None of the Northland firefighters who took part in the Sky Tower Challenge have so far reported any signs of measles.
On May 28, 750 firefighters raced up the 1103 steps of the Sky Tower with 25kg of equipment as a fundraiser for Leukaemia and Blood Cancer NZ. About 50 contestants were from Northland.
The event raised a record $1 million but also caused a public health scare after it was found a Palmerston North firefighter had measles.
Public health staff contacted the Fire Service and brigade chiefs last Thursday, then spent the weekend emailing and phoning every Northland contestant.
They were advised of the symptoms of measles and urged to phone, not visit, their GP if they fell ill.
