Mr Foster is to table his report and an update on the council's financial position which will also outline a proposed strategy to ensure sustainable financial management and delivery of services.
Mr Williams said releasing the report was important for the council as it needed to be far more transparent to the public.
However, Mr Williams said the issues were not disastrous and could be worked through in the hope finances could be put back in order within five years.
The Rotorua Daily Post understands that last week, district councillors were given a brief overview by Mr Foster of the council's financial position, of which they were not entirely pleased.
Mr Williams said the proposed new financial strategy emphasised robust forecasting and simplified reporting to ensure greater understanding by both councillors and the community of the financial impact of council decisions.
Mr Williams said further discussion would be part of the council's upcoming Annual Plan process which would allow the public to make submissions for or against any of the council's future proposals.
