Sherron Sunnex from the Koha Shed said a truck would be leaving Whanganui on Monday afternoon to head up to Kawerau. Another truck was heading to Kawerau from Auckland, collecting goods from Koha Sheds along the way.
"We've been talking with the flood response team up there, and they've told us there's a real shortage of blankets, clothes, baby gear, pillows and non-perishable food," Ms Sunnex said.
"We're asking people for donations of goods because winter is coming and we can't really deplete what we need for people here in Whanganui."
Ms Sunnex said in about a month's time more assistance would be needed for people in Edgecumbe, as they find accommodation and need household goods such as furniture.
People can drop donations off to the Koha Shed, 88 Duncan St, throughout the weekend and up to Monday morning.
Ms Brown said her son still lived in the area and, although he was safe and well, he had had to rescue a good friend from the floodwaters.
"There are a lot of people having a very hard time right now," she said.
Wanganui Auto Wreckers is also accepting goods Saturday and Sunday from 9am to 5pm.
