About 20 international election monitors are expected to oversee the elections in the autonomous Papua New Guinea region of Bougainville.
The United Nations Development Programme is co-ordinating the monitors at the request of the ABG and the Electoral Commission.
The UNDP assistant regional representative Julie Bukikin says there will be observers from Japan, the European Union, Australia, New Zealand and the United Kingdom, as well as bodies like the Australian National University.
Ms Bukikun says they are also helping the election preparations in other ways.
"We have also just this week started training of the candidates' scrutineers. We also looked at how to help women candidates, so we ran a training also to get them to understand the processes, to help with what they would be expecting if they go into elections and they campaign and so forth. The other things we are doing is looking at training and co-ordinating media."
