Solomon Islands is setting up three new overseas missions in Switzerland, Cuba and New Zealand.
The Government says the establishment of new missions is an important strategic move for future development.
The country's ambassador to the United Nations in New York, Colin Beck, says working out staffing is one of the hurdles.
"We have actually already established an embassy account in Cuba, we've looked at the administrative arrangement as well as accommodation. So really, we are talking about time frame in which to deploy staff, and at the moment looking at trying to have staff move as soon as practical, before the end of the year. That applies to both the Havana office as well as to the Geneva office."
While the Ministry of Foreign Affairs is confident the Havana and Geneva missions will be fully operational by the end of the year, it is still not clear when the New Zealand Mission will be established.
