According to the council's website, the toilet is projected to be completed by September 22 this year.
The construction of the toilet comes after Upokongaro business owners asked last year for a public toilet to be installed for travellers to use.
The council is seeking community input on other aspects of the project, like types of plantings and the positioning of cycle racks near the toilet, and will host a community afternoon on Saturday, July 2, from noon to 2pm at the Upokongaro War Memorial Hall.
"Council staff will be onsite to update the community on how the toilet block project is progressing. We'll also be asking for feedback on ways to enhance the new toilet area," property operations manager Sandra Woodhead said.
"There will also be an opportunity on Saturday to look through the Upokongaro War Memorial Hall with staff. Our next task will be to prepare a full business case to establish what the hall's future may look like."
Local hapū Ngā Paerangi, who were consulted in the development of the Upokongaro cycle and pedestrian bridge, will be consulted again on the facilities' development.
