"We are going to need all the help we can get," he said.
F.O.R.C.E co-ordinator Karen Lee said the volunteers, known as E.N.F.O.R.C.E.E.R.s - enthusiastic, neighbour, for, our, real, clean, environment, eradicating, rubbish - have said it is the support of others that ensures they have the drive to keep going until the job is done.
"So it really is the more the merrier."
Anyone who wants to help should meet at the corner of Tauroa and Fairburn Sts at 9am on Saturday. There will be gloves, hand sanitiser, water and a few treats.
