The South African president has promised more help to rebuild communities devastated by the recent floods, but has warned of tougher measures to ensure relief funds are not lost to corruption.
Some 435 people died and more than 50 are still missing - most in KwaZulu-Natal province.
Cyril Ramaphosa said the flooding was evidence that climate change was the biggest threat to the future of humanity.
He said many South Africans were worried that money for victims of the flooding would be lost to corruption - something he described as a great source of shame.
Mr Ramaphosa said real-time audits would be carried out to prevent funds being stolen.
