New Zealand Cricket want Craig McMillan to continue as batting coach of the national side until the end of next year's World Cup.
The Herald on Sunday understands both parties are in negotiations but the arrangement, where McMillan replaced Bob Carter on a temporary basis for this year's West Indies tour, worked well.
New Zealand suffered a relative dip in batting form in the second of the three tests, which the West Indies won, but excelled in the two wins. Five players - excluding Brendon McCullum and Ross Taylor - had series averages of more than 45.
McMillan has since joined the New Zealand A tour of England and Scotland where, in seven completed one-day matches, there have been seven centuries. New Zealand won six of those matches, including a tri-series with counterparts from England and Sri Lanka.
In the four times they've batted first, New Zealand A accumulated 424 for seven, 282, 347-6 and 369-6.
