Boult and Southee's ability to move the ball had England in real trouble, so it was disappointing waking to the news that England - led by Alastair Cook and the devastating Ben Stokes - had recovered so impressively.
Still, that first session sticks in he mind. We've rarely had two such skilful fast bowlers operating at the same time. Some of our partnerships have been more tactical than brilliant - Hadlee's foil was Ewen Chatfield whose metronome-like accuracy did the job.
On other occasions, a fine bowler like the injury-plagued speedster Shane Bond was something of a lone wolf.
There have been a few excellent swing bowlers in our history, although given our conditions there should have been more. Lance Cairns' whirly inswingers to right handers were almost unplayable now and then. Simon Doull had the art. Way back, Bruce Taylor - the enigmatic all rounder with outstanding test bowling figures - could swing it.
But having a fine swing bowler at each end is a treat. One ball from Boult stood out, and it didn't take a wicket. It began to curl towards the slips and then rocketed back the other way mid pitch, drawing a wonderful reaction from the left handed Cook.
The potential of Boult and Southee in conditions ideal for their strengths made it all the more a disappointing day in the end.
