Have you tried just contacting them and asking? Looks like they have a contact form right there on their website, along with phone number, email and facebook page. 

Hey all Craig here from Hostingplus,

To answer your question Jarno, yes this is legit. If you have any questions feel free to contact us via the contact detail at either domania.co.nz or hostingplus.co.nz

Thanks

Yes, I was a Domania customer - had quite a bit of communication with them about a week ago after being advised they are shutting down. I've now changed providers.

Yep it seems they are closing down. We've had a few people come across from them
