It was Fulton's third score of substance in four innings of this series. His combination with left-handed opener Hamish Rutherford - the pair added 79 yesterday - has given New Zealand's batting backbone it has been too regularly missing since the retirement of Mark Richardson.
It gives the selectors a welcome headache. Opening has been a position filled by default rather than demand. The default position has usually been Martin Guptill, recipient of the Sir Richard Hadlee medal at the New Zealand Cricket awards.
Guptill remains a serious white-ball threat, but his test results against quality opposition have been unconvincing.
Fulton may not possess Guptill's talent and youth, but he has runs on the board. This means Guptill's route back into the side when he returns to fitness might have to be through the middle order. In that case Dean Brownlie at No5 would be the most vulnerable.
Fulton's weakness has been a straight-bat waft outside off stump and yesterday it almost had him in trouble early. This time there was enough willow on the edge to carry it over third slip and from that moment he was away.
He was particularly strong through and over the on side, punishing left-arm spinner Panesar with a mixture of slog-sweeps, pulls and one sweetly timed flick off the pads that zinged through midwicket for four.
It's the push to mid-on he'll remember longest, though.
