Hagley Oval groundsman Rupert Bool is hoping Christchurch's wicket will stay greener for longer than in the first test in Wellington.
A lively wicket turned dead within a day in Australia's win over the Black Caps in the capital.
Bool told Radio Sport the different soil may be a factor, but the weather doesn't look like it will burn the grass off quicker throughout the second test.
Bool said overcast conditions allow a green wicket to hang around for longer.
He added they don't have anything special planned for Brendon McCullum's final test, apart from preparing an excellent ground.
