Thank you. I have searched images and have not found an Aristea that is similar. I have attached a detail of one flower - note prominent anther & stigma; three part stigma; numerous flowers & buds in a cluster, unlike the pairs in Aristea.
Looks to me to be Libertia caerulescens. There are several Libertia species native to New Zealand but this one comes from Chile. You cans see some of the other species on my website at http://www.cfgphoto.com/photos-libertia-3089.htm
