The Jewish Federation of Greater Pittsburgh will donate NZ$966,972 to the victims of Christchurch's mosque attacks in March.
The federation started fundraising for the Muslim community after the attacks which killed 51 people.
In a statement at the time of the attacks, the Jewish Federation of Great Pittsburgh posted on its Facebook page that the community was shocked and deeply saddened by the horrific Islamophobic attack in Christchurch.
"We stand in solidarity with the Muslim community in Christchurch, in Pittsburgh, and around the world."
Jewish Federation chief development officer Brian Eglash said it started the fund because of the Muslim community's support after the attack on worshippers at the Tree of Life synagogue in Squirrel Hill in Pittsburgh in the US, which killed 11 people last October.
