The gender gap for pay is closer in Wanganui than nationwide - though both men and women in the region are well down on the median national wages.
Women in Wanganui and Manawatu had a median weekly income of $412 in 2014, 45 per cent less than the men's $652.
However, nationally the difference between the genders is 49 per cent, with women at $464 and men $767.
Whanganui Chamber of Commerce president Raewyn Overton-Stuart believed the city's shortage of top salaries had brought the medians down.
"In general, higher paid jobs have been drawn away from the region," she said. "That's certainly a need for us to attract those kind of businesses and, therefore, jobs.
