Both courses are taking place at VASANOC House in the Pacific nation's capital Port Vila.
VASANOC is hoping that the country's sporting federations will send a coach to the training.
The organisation said it was taking a "different approach" to training coaches following last year's Pacific Games in Samoa.
This will include a focus on areas not necessarily "sport specific".
Sports nutrition will be led by New Zealand's Rachel Scrivin, a registered dietitian.
"I believe that this nutrition training will be of great benefit to the coaches," she said.
"They will have a better understanding and knowledge in advising their athletes regarding the types of food to take - and when and what amount to take, so they maintain fitness and hopefully perform and achieve better results."
The injury prevention course follows a session on first aid which was held in November.
