Many are on the brink of starvation amid the strict regime and the worst drought in 30 years.
World Vision New Zealand national director Grant Bayldon said Afghanistan was now likely the world's worst humanitarian crisis.
"[Years of drought] mean crops have failed and then with the Ukraine crisis going on, it's meaning that the price of grain and getting it into Afghanistan has skyrocketed. People have less money and food is more expensive," he said.
The average household income was just $1 per day.
