Mr Ward said he was felling trees not far from the enclosure when he heard somebody yelling for a cattle prod to be taken to the enclosure.
When he got to the enclosure with the prod he saw Abu ``tossing'' Mr MnCube around.
He hit the big cat on the nose with the cattle prod and was amazed that it had little effect on the beast. Abu continued to attack Mr MnCube so Mr Ward got a shotgun and three shots were fired at the tiger, then another three or four shots were fired before it finally let go of the prone keeper.
Mr Ward said a 4X4 was then backed into the enclosure, but its path was blocked by a log and as Megan Busch, daughter of then park owner Patricia Busch, was trying to move the log, Abu went for her.
He had to pull Ms Busch out of the way to prevent the tiger getting her and the cat reached the gate moments after he closed it.
Abu was then forced away with a fire extinguisher and Mr MnCube's body recovered and taken to an ambulance that had arrived at the park's front gates, but he was dead by that time.
Mr Ward said he then went back to the enclosure and Abu was still alive so up to four shots from a rifle were then needed to finally kill the tiger.
Mr MnCube's partner Sharon Arnott may give evidence in the hearing this afternoon. Coroner Shortland said he would reserve his findings in the case.
