Building sites make a lot of surplus. Most of it goes in a skip.
A job over-orders by 15%. The client changes their mind about the tiles. A house gets stripped before demolition. Right now that material sits in a yard until someone throws it out, or ends up on Facebook Marketplace between a couch and a trampoline. Leftover is one proper place for it.
Real material, from the people who actually have it, with the quantity, the region and the GST already in the price. That's the whole idea.
Who it's for
Builders, chippies, sparkies, plumbers, tilers, roofers and landscapers with material left at the end of a job — part-packs, short lengths, the extra bale, the pallet that never got opened. Renovators clearing a strip-out. Businesses winding down and emptying a shed.
On the other side: anyone who needs six more sheets of GIB to finish a room rather than a whole pack, a matching weatherboard profile for a repair, or a discontinued tile to patch a bathroom. Trade to trade, and trade to DIY. Post what you're clearing, or post what you're after and let it come to you — Leftover works both ways.
Region comes first
Building material is heavy, low value per kilo, and almost always collected in person. Half a pallet of pavers in Whangārei is worth real money to someone in Northland and nothing at all to someone in Invercargill. So region sits beside category as a primary way to browse, not buried in the small print of a listing.
Every listing carries one of the sixteen official New Zealand regions, plus the town or suburb it's actually sitting in — which members can see once they're signed in.
Quantities, units and GST
Partial quantities are the whole nature of leftovers. Nobody is selling one of anything here — they're selling 18 sheets, 40 lineal metres, or most of a pallet. Every listing says how much there is, what a unit is, and whether the price buys the lot or buys one of them.
And “$450” means two different things depending on who is selling, so Leftover settles it once: every price on the site includes GST if there is any GST to include. No “plus GST” sprung on you at the gate, and nothing to work out before you compare two listings. If you're registered and claiming it back, that comes off the seller's invoice the same as it always did.
Free to list, honest about the rest
No listing fees and no subscription while we build this — list as much as you like. And we're straight about what Leftover is: we connect buyers and sellers, we don't sit in the middle of the deal. No payments, no escrow, no delivery, no commission. How to trade safely is worth a read before you meet anyone — see Trust & safety.
