Pleurotus species
versus Panus purpuratus
Several fungi from the Pleurotus genus are found growing on wood in New Zealand, but most have not been described down to the species level. (Ian Hood: Fungi on Wood in New Zealand, 1992).
From above they are brown, sticking out from the wood. The stem is to one side of the canopy.
From below they show an attractive fan of gills and a slightly woolly stem.
Clive Shirley says by email 16 February 2007:
"Your Pleurotus species is Panus purpuratus which is a polypore but don't ask me what a Polypore is doing with gills."

Shirley Kerr says on her web site the name has been changed from Pleurotus, but her Panus looks rather different from Clive's and my "Pleurotus":

Further email from Clive Shirley 16 Feb. 2007:
I came across this fungus a long time ago and also thought it was a Pleurotus. I could never figure out why I could not id it as we only have 6 species of Pleurotus in NZ and only one has purple colouring. This fungus is common in Kirks bush as well as Murphy's bush. It was there that I first found it nearly 20 years ago!
It was not until I saw Shirley's image that I realised what it was. As far as I am concerned it matches the description on Landcare's site reasonably well. Her images have very saturated colours so look much more purple then it is. I have noticed that the form it takes depends on where it grows. Those that grow from the side of a log look like our photos, with the stipe short and off centre. Were when it grows from the top it's more funnel shape, with a longer central stipe.
(The example imaged above in 3D comes from Murphy's Bush - John Wattie)
email from Shirley Kerr 17 February 2007:
Hi John
I have had a look at your photos and they are of a pleurotus. So is Clive's "Panus purpuratus". I have discussed this one with Clive previously, but he remains unconvinced that his is not a Panus. Panus purpuratus is quite distinctive when the correct species is observed. The cap is circular, and funnel-shaped as seen in my photos. They do not have the stem attached laterally like a pleurotus. I have found them on 3-4 occasions, always over the late-spring-summer if it had been wet for a few days. Until Clive sees the real one, he is going to keep calling his Pleurotus a Panus. They are a polypore, though over the years different mycologists have classified them differently. They have been swapped back and forth between the basidiomycetes and polypores several times!
I hope that helps to solve the confusion!
Kind regards Shirley
