A truck in Tonga returning from distributing aid to those affected by Tropical Cyclone Gita has been attacked.

Radio NZ reports in the early hours of Wednesday morning a rock was thrown at a truck when returning from distributing aid.

Tonga's National Emergency Management Office director says there cannot be an even distribution for everybody but at the same time they are trying to reach out to all the affected people.

But he adds the incident is still concerning.
