The number of insurance job vacancies in the south east rose by 30% last month, according to figures published by HR consultancy Alexander Lloyd.
However, the number of staff looking for work in the insurance sector fell by 16%, and the number of permanent positions filled fell by 30%.
The rise in the number of jobs is largely due to the growing trend of insurance companies moving back office functions to the area.
Seeing as more and more companies look likely to relocate to the south east, recruiting could become a problem.
Insurers and recruitment consultants are said to be concerned at the fall in candidates as the number of positions already outstrips suitable candidates.
Alexander Lloyd operations director Neil Quarendon warned: "With a shortage of good workers in this sector, there is a danger that employers will relax their high standards in order to get the work done."
He added that the insurance industry should work on extending its appeal to "young people about to embark on their careers" to aid recruitment.
