Save the Children says teachers in Fiji will need ongoing support as they deal with children affected by Cyclone Winston.
The organisation has been providing safe learning spaces to schools and communities, which include arts and craft materials and toys, as well as school bags to children who have been left with nothing.
A child and family psychologist, Melanie Patterson, who returned to Christchurch from Fiji on Tuesday night, said Save the Children has now reached communities in the remote Lau group and is training teachers from a range of islands and villages.
"Teachers are going to be sort of in the front line of supporting and helping students. And I know that there is a lot of work going on in the background as to getting resources out to teachers on how to look after themselves but also how to support the children."
The Government said while most children are back at school there are some remote schools that sustained heavy damage and children there will remain at home for the time being.
