Chris Wood has netted six goals in 15 matches since signing for Leeds United.
Wood scored the winner for New Zealand against Oman in their most recent outing, and Hudson has been impressed by the striker.
Hudson says that Wood is growing into a more prominent figure for New Zealand every time he joins up on international duty, and he is also impressed by the target man's patriotism.
"Woodsy is great to deal with. Every time he comes into camp he shows how passionate and patriotic he is," Hudson said.
"He loves playing for New Zealand. He is great to have in the team and is becoming more of a leader all the time. To have Chris Wood in our side is huge for us."
Wood captains his country, despite still being only 23, and he has an impressive scoring record at international level.
The former Leicester City man has netted 14 times in 40 appearances for New Zealand, and he seems to be growing in confidence by the game.
Wood made an inconsistent start at Elland Road, but he has worked well with Mirco Antenucci since Steve Evans took charge and switched to a 4-4-2 formation.
Wood scored in his most recent appearance for the Whites, and he will hope to extend his scoring run after the international break, when his side take on Rotherham United next weekend.
