Despite growing numbers of female accountants, women within the industry are paid 30 per cent less than men.
The New Zealand Institute of Chartered Accountants annual survey showed a 3 per cent increase in the number of female accountants.
Women now make up 42 per cent of the industry, but are paid on average 26 per cent less.
The NZICA Marketing and Human Resources director, Jeana Abbott, said the results enabled members to start working on addressing and fixing this.
Abbott said although she was aware of the gap, she was surprised by its extent.
