the match also began to fall.
The partnership was finally broken, after exactly 510 minutes, when South Africa-born Watling was trapped lbw by Mohammed Shami off his third delivery with the third new ball.
McCullum needed occasional treatment for his chronic back injury throughout the fourth day as he continued to play an innings of outstanding diligence and concentration. He had batted more than 12 hours by stumps in the longest-ever test innings played by a New Zealand batsman.
India went into the match with three fast bowlers and, as the sixth wicket partnership stretched on, their workload had become almost intolerable. Ishant Sharma (39 overs), Zaheer Khan (33 overs), who had taken 3-129 at stumps, and Mohammed Shami (40 overs) had been progressively worn down, though they worked hard.
Spinner Ravindra Jadeja bowled 49 overs and took 1-108 as New Zealand scored 318 runs Monday for the loss of only one wicket.
