Deputy Electoral Commissioner, John Kalamoro, says by law the review must be done every 10 years.
The next review is two tears overdue.
Kalamoro said the organic law allows for more than 89 open electorates but not more than 120.
He said the review of boundaries needs to be conducted immediately and 20-19 appears to be the best time because it is not too close to conduct the 2022 elections.
