Colin De Grandhomme offered a reserved review of his blistering maiden Test century after taking the game away from West Indies at Basin Reserve.

New Zealand ended day two in Wellington on 447-9 -  lead of 313 runs - thanks in no small part to De Grandhomme's 71-ball hundred.

The all-rounder was immediately on the attack and hit 11 fours and three sixes in the second-fastest century by a Kiwi in Test cricket.

However, De Grandhomme was a much more measured presence when analysing his stunning knock, which was ended at 105 by Roston Chase.

"Obviously, it helped getting a couple of boundaries early but they were there to go, so I had to put them away," he said.

"It should be a pretty simple game, so I try to keep it as simple as you can, and it should be easier.

"Ninety to 100, it's not a big difference for me.

"If I get a good ball and get out on 99 instead of 100 it's not a big issue for me.

"Today felt pretty good. The sticks [bats] I've got at the moment are pretty good so I feel confident with them."
