New Zealand coach Graham Henry has told his players that they must improve ahead of their opening Tri-Nations match against South Africa next weekend.

The All Blacks warmed up for the tournament with Australia and South Africa by securing a 60-14 win over Fiji on Friday. Despite the margin of victory, Henry feels his side still has plenty to do ahead of their first Tri-Nations match on Saturday.

"A lot of individuals played well but I think we've got a lot of work to do as a team, which is understandable. There is plenty to work on but to score 60 points is pleasing," Henry said.

"Playing the Springboks will heighten the intensity. If we don't increase our intensity and accuracy, particularly at the breakdown, we're going to be in trouble."

South Africa opened their Tri-Nations campaign with a 39-20 loss at the hands of Australia today.
