OMG you found some Anubias afzelli I heard somewhere that it is very hard to come by in NZ. It's now in good hands too
There are two types of Mayaca common in aquariums: M. fluviatilis and M. sellowiana. Both of there plants are green, and M. sellowiana has longer, wispy leaves that give it a fluffy appearence. I'm not sure if they're currently in NZ. There are a few more species, and I think there is a red Mayaca (not sure though), but in NZ red pine is always Rotala wallichii or similar types of Rotala.
Mayaca fluviatilis - Green Pine
Mayaca sellowiana - Green Pine
Rotala wallichii - Red Pine
