Airbnb owner Rochelle Zajko said she found out about the fire on a community Facebook page, and did not know Midwood and her daughter before it happened.
Zajko said many people were posting on Facebook and asking how they could help.
After the fire happened, Speedy said she was supporting Midwood, who was getting "inundated" with people messaging and asking if they could bring her clothes.
"I decided to take it off her hands and just have a drop-off point here [at Best Start Ōmokoroa] where everyone knew, [so] Chanelle didn't have to keep teeing up with everyone."
Donations included clothes, bedding and kitchenware, she said.
"There's been an amazing response."
Donations are still welcome at BestStart Ōmokoroa.
On Thursday, Fire and Emergency community risk manager John Sutton said crews responded to a "well-involved house fire" in Aongatete at 11.32am on Monday.
Three fire trucks, one operational support unit and a fire investigator attended the scene.
Sutton said the investigation into the cause of the fire had been completed and was classified as "undetermined".
"The likely cause was electrical," he said.
"This is a timely reminder for residents to have working smoke alarms and an escape plan. In a real house fire, you have less than three minutes to escape your house."
