Ms Ardern said over 50 per cent of schools in Tonga were damaged in the cyclone.
In a press release Ms Ardern said the package will, "Our package will support the Government of Tonga’s recovery planning and will focus on the restoration of the electricity network and helping children continue their schooling".
"Cyclone Gita destroyed or partially damaged around 2000 homes in Tonga. Many communities are still without power and schools are without essential materials. It is a huge burden on so many families in Tonga and we are helping them recover."
