Police will today start to interview first responders to the scene of the hot-air balloon tragedy in Carterton as they continue the investigation into the disaster.
Eleven people lost their lives when the balloon carrying them on a dawn ride caught fire and plunged to the ground on Saturday.
Seven bodies had been taken to the mortuary at Wellington Hospital and four remained at the scene this morning, Wairarapa Area Commander Inspector Brent Register told Radio New Zealand.
Following the identification of the victims and witness interviews, police would today start the next phase of the investigation by speaking to police, ambulance and fire staff and members of the public who were the first to arrive on the scene, he said.
As part of the investigation, they would look at how the accident happened and how similar accidents could be prevented in the future.
A condolences book has been set up in Carterton's town hall for victims' families, who were being supported by officers.
"We're looking after them as best we can''.
Mayor Ron Mark said there had been an outpouring of support for the families since the tragedy, which had "hit Carterton hard''.
"They were people we know. We love them dearly. They are widely known, highly respected, much loved,'' he said.
Mr Register said it was too early to say if any charges would be laid.
The investigation, by at least five agencies, was expected to take months to complete.
