If you ask Black Caps pace bowler Neil Wagner, he has bowled better but "things just happened" - such as two wickets from his first three balls.
Wagner picked up opener Alastair Cook's wicket with what he described as a wide half-tracker. Cook whacked it straight to Hamish Rutherford, though.
The next delivery was a beauty and definitely part of the plan. If you are going to get Kevin Pietersen's wicket, then your best chance is to strike early.
Wagner speared in a full delivery which swung and trapped the classy right-hander in front for a first-ball duck.
"Getting Kevin's wicket was massive during the warm-up game [in Queenstown last week] but getting it in a test is even better," Wagner said. "If there is any wicket you want that was the one. I'm real pleased with that.
