Their call for a 50-50 system comes as the National Council of Women turned 38 years this week.
Council President Leias Cullwick says locking down equal representation in parliament will allow ni-Vanuatu women to have a real say in the decisions shaping their lives.
PRN reports Vanuatu has only had five women politicians win at the polls since independence in 1980.
It's currently one of only three countries in the world with no women in parliament.
