I haven't included many NZ titles on this blog, so I have taken it upon myself to produce an infographic of NZ fiction covers, inspired by this post. The titles I've included were all published in 2011, and are all classified as "general or literary fiction" according to their metadata. There are 23 in total.
As you can see, the covers are heavily weighted towards brown/grey, with red coming in as a popular second choice. I can literally count the number of titles that are not brown or red on one hand. Looking at this, it doesn't seem that surprising that NZ fiction has a reputation for being dreary and depressing.
Close-ups of people's faces also seem to be a popular choice.
