England's Paul Collingwood believes he can regain his form in the final Test with New Zealand starting on Thursday.

He made six and two in his first two knocks of the series, and was off-key again on the final day at Old Trafford, but saw England home with a defiant 24.

"I've had a great week with (batting coach) Andy Flower, talking cricket and getting the mind back into a more confident place," he told BBC Sport.

"International cricket is all about confidence and scoring runs."

Collingwood chose to have two sessions with Flower in Durham rather than play competitively for his county.

"You don't often have time to work on things and this was an ideal opportunity to go away and work on a couple of technical things," he said.

"I'm an experienced player now and I'm 100% behind that decision and hopefully that's put me in the best possible mental state going into a Test match."

The 32-year-old all-rounder, who has now had 22 inninngs without a Test century, admits that he has been aware of criticism aimed at him, with many calling for a change in the batting line-up.

"You hear what people say and can get bogged down by it or things in your mind become unclear, but in the end you have to back yourself and I do," he said.

"Plenty of times I've been in this form - in Australia after my double hundred, for example, I was low as low could be and I was nearly dropped from the one-dayers - and I came back with with two hundreds and did exceptionally well.

"I can draw on those experiences, what's worked for me, and what worked was rest and working on my technique."

Collingwood feels England have the mental edge over the Kiwis, having fought back from a perilous position to record a six-wicket win in the second Test and take a 1-0 lead into the final match of the series.

"We were absolutely clinical, there was no panic, real intent, running between the wickets and really put them under pressure," he said.

"One of the biggest things was we played [Daniel] Vettori really well, nullified him and hopefully we can continue in that manner and get big scores again.

"It'll be a test of New Zealand's resilience and hopefully we can keep on top of them.

"Momentum is a big word in sport and hopefully there's been a momentum shift our way because that last day and a half was exceptional and hopefully things continue to go our way."

The England one-day captain, who struck three half-centuries on the winter tour of New Zealand had been in danger of missing the opening Test at Lord's this summer with a troublesome shoulder injury, but insists the problem is under control.

"My shoulder is excellent - 100% - after the injections" he said.

"It has reacted really well and I could bowl if need be. Monty's bowling well and the seamers have been doing their jobs so I've only had short spells.

"Over the last year-and-a-half I feel I've done a job with the ball in the Test side and the shoulder won't stop me doing that this time."
