Census officials are out and about visiting those who live in the most remote areas in Northland and did not receive an access code in the mail.
This year's Census on March 6, was held online using an access code sent in the mail, which caused some concern for elderly people and those who did not have access to the internet.
A Census spokesperson said about 4 per cent of Northland households had not received a code in the post due to their remoteness and were now being visited by staff.
Those households are in Te Paki, Te Kao, Hukatere, Motitangi, Paparore, Karikari Peninsula, Panguru, Peria, Kawakawa, the Bay of Islands, Russell, Paihia, Opua, Takau Bay, Ahipara, Pukenui and Te Hapua.
"Teams will be in Northland over the next few weeks to make sure everyone has the chance to be represented."
