The 39-year-old German beauty was due to host her annual event in New York City on October 31, but she called off the party in the days after Sandy hit America's East Coast, reported Express online.
Klum had said that she "didn't think it was right to dress up... And dance" when so many people had lost their homes.
The bash will now take place at New York City venue Finale and will raise money for the Red Cross' Sandy relief scheme.
Tickets will be sold off on auction website eBay.Com to boost funds, and Klum will also volunteer for the Red Cross.
