A new, complete Wakatipu High School uniform can cost more than $800 for girls and about $650 for boys.
Queenstown community support centre Happiness House has been selling them almost as fast as they arrive on the racks - and more outgrown or unwanted ones would be greatly appreciated by their new owners, Happiness House manager Nicki Smith said.
With winter approaching, the centre is looking for more winter Wakatipu High School uniforms - especially expensive items such as girls' kilts.
"We only have two kilts left at the moment," Ms Smith said.
They can cost up to $269 new - but can be bought from the centre for much less.
An entire second-hand uniform would cost "about half of a new one" if bought from the centre, Ms Smith said.
The uniform scheme also delivers money back to the original owners - when items are sold they receive 80% of the money with the centre keeping 20% to cover operating costs.
Ms Smith said the centre had been very busy this year - monthly records of visits to the second-hand "store" were on track to top 820 for March.
"That is the most we have ever recorded so far and I think we will have more people this month," she said.
All second-hand goods were always gratefully accepted but, as winter drew nearer, donations of warm blankets, children's winter clothes and shoes and curtains were the greatest needs.
"A lot of people use curtains to insulate their homes so if people have some old ones lying around they are always helpful," she said.
This year the centre will also take donations of second-hand electric blankets, thanks to an electrician offering his time to test them.
"We have always thrown them away in the past because we haven't known if they are safe or not," Ms Smith said.
