Since a deadly earthquake hit Haiti in January, hundreds of international aid agencies have flocked to provide relief.br br Nonetheless - much needed aid has failed to reach thousands of people.br br 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.br br And yet the UN's top relief co-ordinator has recently criticised his team in Haiti, saying it has been "disorganised and inefficient."br br 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.
