Committee chairman Pastor Dave Moore said members of the community had always been amazing when it came to volunteering their time.
"We've still got opportunities for people to help with hosting on the day, such as welcoming people and helping them in sitting at tables, and also people who can come towards the end and help with the clean-up and putting everything away."
Moore said Christmas might not be such a happy time for some because of stress or loneliness.
"To be able to give a couple of hours out of the day and come together to celebrate as a community is pretty cool."
People who are keen to volunteer on the day can register at the Rotorua Christmas Day Community Lunch Facebook page.
Those who want to attend can register on the Facebook page or at the Citizens Advice Bureau.
