The American New Zealand Association has raised more than half a million dollars from donors in the United States.
The Association's chair Ian Phillips released the figure to a large gathering attending a fundraiser for quake relief in New York on Sunday night.
He says hundreds of donations are being made via the organisation's website.
Mr Phillips says the support has come from all over the US, with people raising funds though events from bake sales to large benefit evenings.
He says the Australian community in America has played a key role in the fund-raising.
Mr Phillps says the Association is working with the New Zealand ambassador to the US, Mike Moore, and other American organisations to help direct funding to practical assistance for people in Christchurch.
Scotland pays tribute
The people of Christchurch will be remembered on Monday at St Mary's Episcopal Cathedral in Glasgow.
The church is almost an exact likeness of Christchurch's Anglican Cathedral and both were designed by the English architect Sir George Gilbert Scott in the 1850s.
St Mary's Cathedral Provost, the Very Rev Kelvin Holdsworth, says a benefit concert held recently for Christchurch raised a considerable amount of money.
He also says specials prayers will be offered at Monday's service.
