On the day-night test format which made its New Zealand debut in the first test, Boult said the pink ball was still an issue.
"There was a blatant difference between bowling throughout the afternoon and once the lights came on," he said.
"The pitch almost seemed to do a few quirky things, a bit more pace, when the dew had settled on the wicket.
