Volunteers from Auckland's Muslim community will be up early tomorrow, picking up the mess from New Year's Eve celebrations.
About 50 volunteers have offered to pick up bottles and other litter from parks in the city centre.
Imam Mustenser Qamar said it is an effort to show the Muslim community making a useful contribution.
He said the Ahmadiyya group is committed to promoting a positive view of Islam.
"We feel there is more of a need to raise our voice and show that there are Muslims out there who are genuinely loyal to the country and also genuinely against what these extremists are doing."
Qamar said it doesn't matter to his group, that they won't be the ones making the mess.
"We don't drink but that doesn't stop us from clearing up and helping to keep our country clean. In the past we have been picking up beer cans and beer bottles and stuff."
He said starting the year with a charitable act is a sign of how the group plans to go on.
