Like the Boks, they have gone backwards and Argentina are possibly the closest thing beneath the Equator to a credible opponent, and even they were beaten by 35 points last week.
England could be a threat but we won't find out until 2018 at the earliest and, given their coach Eddie Jones' track record, they may be exposed as not being quite as good as they think they are long before then.
There's no point in pretending, the All Blacks are some way the best side in the world and it will take a supreme effort to beat them. Either that, or it will take the All Blacks to have an off day - quite a bad one - for them to be beaten.
And this is the danger now for New Zealand. They have to drive their standards in the face of slightly-underwhelming competition. They have to continue to ignore their opponents and believe only that they are vulnerable, as beatable as anyone, and, most importantly, ignore the growing noises from an enthused rugby fraternity that is increasingly talking up the All Blacks as invincible.
All Blacks coach Steve Hansen admitted he has been surprised at how far his team have come in a short time but will continue to drive home the need for complacency to be kept at bay.
"If I am being really honest, no," he said when asked if he imagined the All Blacks would be this good at this stage of the season. "I knew we had some really talented people but we had also lost some talent.
"And the thing we lost the most was experience. I am really pleased at how Reado (Kieran Read) has stepped up to the plate and we have probably gone to another level because he has been open and flexible in his thinking and that has allowed him to lead subtly differently to the guys who have left and who did such a wonderful job for us for four years.
"I said it before and I will keep saying it, when you cut down big trees that cast big shadows you will always find that guys will stand up and our guys are standing up and leading well, preparing well and the coaches are coaching well. All the other staff are doing everything that they possibly can to the best of their ability so the machine is ticking over quite nicely and, as a result of that, we are playing good rugby.
"We have to keep asking ourselves to get better every day and, if we do that, then we are a chance."
