Sports Minister Jonathan Coleman says Rio is not risk-free but reports of violent protests, coaches being beaten and bullets coming through tents at the Rio Olympics have not raised his concerns about the safety of New Zealand athletes at the Games.
Coleman said he was confident the New Zealand Olympics team management had taken all measures possible and the athletes were well briefed on security and health precautions.
He expected he would be briefed of any incidents involving the New Zealanders after he went to Rio himself on Tuesday.
"In a city like Rio there will be stuff that happens, that's probably the reality of it. But around an Olympics, you've got 80,000 police there, you've got well over 100,000 visitors.
He said in the lead up to the Games, the Ministry of Foreign Affairs had helped with risk assessments and kept an eye on political developments such as the impeachment of President Dilma Rousseff, protests, and infrastructure problems.
