After seeing off England 24-21 at Twickenham, they defeated Scotland 24-16 in Edinburgh and then rounded off their tour with a blistering finish to beat Wales 34-16 in Cardiff.
Read was among the scorers as the All Blacks scored 19 unanswered points in seven minutes against Wales, who would have been hopeful of victory after leading 16-15.
And so New Zealand will return in less than a year's time as the World Cup favourites but back-row Read insists the difference between living up to their billing and not will require work.
"It's tight at the top. Anyone in the top six or seven nations are good enough. We have just to keep playing well and keep improving. The All Blacks is the team you want to play for, and when you come in you want to add to the legacy that has gone before you.
"The expectation is always there as an All Black side. When you run out you have got to win that game, no matter who you are playing against. That is the expectation we have as players and as a team every week.
"You make sure you prepare as best you can, and in the end it is about going out there and playing well. There are really no excuses from our point of view."
