Community groups and government organisations are doing their final push for the 2018 Census.
Stats NZ wants 70 per cent of all forms filled in online, but anyone could ask for a paper form instead.
It said on Monday more than 1.2 million people had done their Census online, with a day to go.
Rotorua Citizens Advice Bureau manager Jane Eynon-Richards said by mid-afternoon today, Census day, at least half a dozen people had come in saying they still hadn't got a code.
"They were from all over town and often older people."
