"My 9-year-old daughter said 'I wish I could do something' and that was it. I went down to Countdown, bought some bottles, and started sharing Facebook posts."
Mr Hafoka than approached schools asking for donations, which he will pick up on Friday.
He has organised two freight options to get the supplies to the South Island on Monday.
"People here, everyone just wants to help, but they don't know how," Mr Hafoka said.
"A lot don't want to give money to an organisation, they want to give something physical."
Mr Hafoka said people could drop donations to him at the old weigh station on Maunganui Rd, at his office at Tarpaulin Makers (BOP) on Portside Dr, or at Russell Hardie Property Management at 147 Old Taupo Rd in Rotorua.
He can be contacted on 027 200 7932.
