When the night watchman goes on and makes 50 you know you are in for a long day in the field.
And so it proved for Otago.
Northern Districts resumed its first innings on 162 for one and pushed on to a record score at Molyneux Park of 547 for seven.
It is its sixth-highest score in its history and it leads Otago by 205 runs with a day to play.
Opener Henry Cooper chopped his way to a maiden double ton.
The right-hander cut anything that pitched even close to short and you do not want to give him width when he is in that kind of form.
Later in the day he really cut loose and dispatched a couple of sixes over long on. But more impressively he switch-hit Anaru Kitchen and Michael Rippon over the rope for six.
Mercifully, he was out for 200 when he tried the shot again. Rippon trapped him lbw but it was a pyrrhic victory.
Cooper and Bharat Popli had piled on 179 for the third wicket by then.
And that came on top of a 107-run stand by Cooper and night watchman Brett Randell (50).
Randell scored his second first-class half century to go with the maiden five-wicket bag he picked up in the first innings.
Popli was out shortly after Cooper for 86. His wicket cleared the way for the middle order to chip in with some quick runs.
There were also some quick wickets for Otago as well.
Rippon's tough day took an upward turn. He nabbed the scalps of Colin de Grandhomme (21) and Scott Kuggeleijn (12).
But it was the icing on a dog biscuit. His four for 142 from 37 overs was hard yakka.
Otago could be in for a touch more pain this morning.
Northern Districts may elect to bat on and put the Volts under even more scoreboard pressure.
However, claiming 10 wickets could prove a difficult task.
Kuggeleijn and Brett Hampton have picked up injuries, so the visitor's bowling stocks will be tested.
Volts coach Dion Ebrahim felt his side stuck to its bowling plans well but conditions were favourable for batting.
"I'm more than happy with the way we went about the bowling and our execution.
"We missed a couple of chances which may have reduced the score, but the score was probably a true reflection of where the pitch is at.
"[Cooper] batted pretty well. It was a pretty chanceless performance. He showed some really good discipline in good batting conditions."
