Umaga delays retirement decision Scotland 10-29 New Zealand

"The grand slam and what we have done previously has capped a great year, which is delightful," he said.

"It's just superb. They wanted to set some history in New Zealand and they have done that, something very special.

"We were disappointed in our accuracy against Scotland but we are delighted with what we have achieved."

Captain Tana Umaga acclaimed the win over Scotland and paid tribute to everyone involved with his all-conquering team.

The Scots played exceptionally well, it was the best game of the tour Graham Henry

"It has been an historical occasion for us and we have achieved four in a row," he said.

"The whole side can be proud of what we have achieved. It is something that no-one can take away from us.

"But it has been hard work and we would like to thank everyone - friends and family - who have come over to support us.

Scotland match reaction

"To the Scottish public, we never feel more welcome than when we come to Edinburgh so we would like to thank them too."

Henry has been able to blood a number of young players on this tour and is now confident he will have a squad of 30 to challenge for the World Cup in 2007.

"The objective of the tour was to try and develop players," Henry added. "The forward pack that finished up on the track was a very young.

"They are going to get better players for the experience and the Scottish boys gave them a big run for their money."

And Henry paid tribute to Scotland for the way they fought back from 3-22 after a disappointing first half.

"I thought the Scots played exceptionally well," Henry said. "It was the best game of the tour. We could have played a bit better I guess but it has been a long year.

"I guess we always expect perfection and at times we didn't achieve that."
