The New Zealand cricket coach Mike Hesson says its core group of players need to be backed despite being thrashed in two tests against South Africa.
Speaking the day after South Africa completed a series whitewash with an innings and 193-run win in Port Elizabeth, Hesson says it's important not to rush into drastic changes.
He identified the failure of the top order batsmen against South Africa's world-class fast bowling attack as one of the main reasons New Zealand had been outplayed.
However Hesson has praised the performances of Dean Brownlie and BJ Watling, who had batted well in extreme conditions.
Although Hesson says captain Brendon McCullum would almost certainly move back to the middle order in the forthcoming series against England, he didn't believe in wholesale changes.
He says it's about giving players confidence in selection and backing them during a period of time as long as you see improvement.
Hesson added they want to invest time into their core group, although performance needs to be judged.
