There's concerns about how the closure of a South Auckland paper mill will affect kerbside recycling.

Oji Fibre Solutions will shut up just a week before Christmas - with the loss of 75 jobs.

It's the latest manufacturing firm challenged by high electricity costs, following Winstone Pulp International closing two mills.

Auckland Council waste solutions general manager Parul Sood says paper and cardboard collected from homes hasn't been going to the Penrose mill.

"It goes to various markets in Asia, because they sell paper and cardboard as a commodity in the markets - and we get a good price for it."
