Thank you very much for all of the tips. They ended up getting in touch with some tracker based in Nelson who helped them out with some other pointers. Like not calling its name (unsure of the reason). Sounded like the well worn clothing worked as well. Possibly slept on some of it but got scared off the next morning.
Facebook did help with sightings.
Ended up just camping in the car on the second night and heard his collar come by so put their hand out and then slowly opening the door.
Cheers again.
