Since a deadly earthquake hit Haiti in January, hundreds of international aid agencies have flocked to provide relief.

Nonetheless - much needed aid has failed to reach thousands of people.

To solve the problem, the United Nations has been holding meetings between more than 300 relief groups in the country - aimed at improving delivery co-ordination efforts.

And yet the UN's top relief co-ordinator has recently criticised his team in Haiti, saying it has been "disorganised and inefficient."

Al Jazeera's Steve Chao reports from Port-au-Prince, where six weeks after the disaster, many Haitians say food and medical assistance are still in short supply.
