What we have is the Hiller FH-1100 having its 100 hour & annual inspection done at Heli Maintenance at Christchurch. Top pic showed the tail rotor drive shaft cover open, and the second shot is a closer look at the rotor head.
Chopper77 correctly named the Type/model.
I make the MCTOW 1147kg, as taken from the CAA web site.
I am however happy to cough up one chocolate fish to Chopper77 - if you care to send me your snail mail address.
