About $37 million remains available to be handed to efforts to help rebuild Christchurch after the February 2011 earthquake.

The Christchurch Earthquake Appeal Trust says it has given $47.26m of the $100.73m raised in the government's official global fundraiser since February 27, 2011.

It says the money has gone to 112 separate projects, in areas such as heritage and culture, sport and recreation, spirituality and faith, economic revitalisation and education.

A further $53.47m remains, but $14m is already pledged to specific projects, leaving $37m still to be allocated.

The money was raised through donations from families, individuals, clubs, businesses, governments and leaders from around the world.

"Appeal funds remain available for projects and speaking as a Cantabrian as well as a trustee, this is positive," Christchurch Earthquake Appeal trustee Dr Rod Carr said.
