A body has been found by searchers looking for a missing firefighter under a collapsed house in Muriwai.

It's been more than 24 hours since Dave van Zwananberg went missing beneath the wreckage.

A colleague of his also caught in that slip, Craig Stevens, is in a critical but stable condition in hospital.

The body located today was yet to be retrieved and identified.

The United Fire Brigades Association Chair Peter Dunne spoke to Max Towle.
