He groans, he bleeds and if things go really wrong, he can even die on the table.
A $150,000 mannequin named "Thomas" is a shining star of the new paramedicine department of AUT University's Manukau campus.
The unit opened this year to bring facilities closer to the Maori and Pacific community it hopes to attract, with state-of-the-art training suites including simulation rooms and a full-sized ambulance, plus several mannequins that add real-life intensity - without the risk.
"You couldn't very well practise this on a real person," says the head of paramedicine, Paul Davey, as he gestures at the mannequin, which has just lost its lower leg in a pretend logging accident and is bleeding all over the floor.
"But when our students graduate this could be the first job they go to - or they might not get it for five years."
