Having been in the position to force a victory on the final day, New Zealand's lower order surprisingly caved in to some stifling England tactics, before recovering to set up an intriguing final day.

Controversially declining the chance to take a second new ball, England persisted with Ashley Giles, who bowled into the rough from over the wicket for most of the day.

Ashley Giles finally rediscovered some confidence on Sunday

Meanwhile Steve Harmison produced a wonderful burst of three wickets in four overs to dismiss Mark Richardson for 101, Nathan Astle for 49 and Daniel Vettori for 5.

It seemed as if New Zealand were not entirely sure of their tactics when they resumed after the tea break.

Richardson, who has clung to the crease like a limpet for more than 13 and a half hours in the match, failed to score a single run in half an hour after the break, and was lured into flashing outside the off stump.

It was a rare indiscretion resulting from the pressing need for his team to bat more positively.

In Harmison's next over, Astle followed suit by edging to Jones and, even now, Marcus Trescothick decided not to take the new ball.

Vettori never looked comfortable and was beautifully caught by Geraint Jones, low to his left, for five.

This left Cairns to cope with the tail, and he had little option but to go for his strokes. Having reached 14, he tried to pull Giles over midwicket for six, but was brilliantly caught by Butcher at full stretch as he ran forwards.

Suddenly, having removed all the slips and opted entirely for defence only half an hour before, England were right back in the match and needed just one more wicket.

Giles deserves a lot of credit for his marathon performance - but, importantly, he was actually treated as a real bowler for the first time since England were in Sri Lanka before Christmas.

Since then, he has been little more than the man who has to come on briefly to raise the over rate, and his confidence was rock bottom.

After Simon Jones removed the dangerous Brendon McCullum just four short of what would have been an excellent maiden century, Giles took two wickets in three balls.

First, Scott Styris was snapped up by Hussain at silly point - Giles's first wicket since the first Test in the West Indies - and two balls later McMillan was also caught by Hussain as he bottom-edged a sweep into his pad.
