What does the “DO NOT USE FOR NAVIGATION” indication mean?

Sometimes when I'm browsing IAC charts online I find a "DO NOT USE FOR NAVIGATION" notice printed on the chart. Not always though.
For example, have a look at the chart for Queenstown RNAV (RNP) Y RWY 05.
See the notice there?
I have always wondered why do procedure designers put these notices on their charts. I find it almost contradictory, since I think these charts are the best source of information that an aircrew can have to navigate/maneuver. Isn't it ironic?
I'm sure I must be missing something.
Can anybody shed some light on this?
PS: These are not SIM charts. These are real charts from the AIP.

I suspect these notices appear on the online versions of charts, because the online versions are not guaranteed accurate. The notice probably doesn't appear on the paper version.

Can't say authoritatively as I'm not familiar with NZ rules but in the US, IFR charts are published every 28 days, thus any chart older than that would be 'Not for navigation'. This one was effective 9 Nov 17. Also, redaining the NZ AIP web site disclaimer, the charts are for 'personal use'. This approach is restricted in that it requires GE Aviation approval as well as CANNZ RNP-AR approval. Basically, this is a PBN RNAV approach for airliners with a GE Aviation FMS. So there's no real reason to keep a valid copy on the web site since most of the public can't use it.

Unless it's an obsoleted procedure chart, it usually means that it's not complete. The example you show has only the features pertinent to that approach, and its missing (for clarity) the features needed for any other aviation in that area.
You must use a sufficiently complete chart for navigation; the approach diagram is supplementary to your navigation chart.

In some countries, administrative and legal reasons require that label, because maps officially usable for navigation may need
process used for completion including various warranties, for example:
included map layers collected from their respective sources can be no more than 3 months old
the map got reviews and approvals prescribed by the process – all documented, with clear responsibilities
by adhering with the process, the map received official certification and then catalogization etc.
The same company can produce ad-hoc maps from similar sources, of similar quality which still did not go through the entire (quite expensive) process and therefore they are mandatorily marked as "DO NOT USE FOR NAVIGATION" which is also connected to various legal implications.
So such a label might not inevitably mean that the map is missing something. Even after closer look, it can appear 100% complete. But it should not be used as official navigation aid. For example, if an insurance event will occur where navigation can be at least slightly involved (or even theoretically), finding out that such a map was used for navigating will give aces into hands of the insurance company.

I do not believe the reasons stated in other answers. The only difference between this approach plate http://www.aip.net.nz/pdf/NZQN_45.1_45.2.pdf and other approach plates for the very same aerodrome in the same AIP like
http://www.aip.net.nz/pdf/NZQN_43.1_43.2.pdf
or
http://www.aip.net.nz/pdf/NZQN_45.3_45.4.pdf (also RNAV, but RNAV GNSS, not RNP)
is the type of the approach. The level of details of the map, for example, is exactly the same.
One needs special equipment and a special approval for this approach and cannot just fly it according to the map or select it in a normal Garmin.
The plate misses something important and it is NOT the details of the map. These are the actual minima to be used for the approach (I do not get what other navigation some suggest other than the approach for which the map only exists...). Notice the important notice: Minima figures are indicative only. See CAANZ RNP-AR operator approval for specific procedure minima.
So this approach plate is not enough, more information is needed to properly perform the approach. Not to do other unspecified navigation, no-one would do that, but to fly the approach (or the associated missed approach procedure).

In addition to the other excellent answers, because the publisher expects to be compensated for creating the charts. In other words, they don't want you downloading free stuff, they want to sell you approach plates needed for actual flight. They put this tag on any print or electronic version promulgated for training or general reference.
Right, in addition the publisher is not the CAA itself, but a private company Aeropath, owned by Airways New Zealand, the national ANSP. They have obviously an agreement.

The simple answer is that the chart is or will become outdated. As a pilot you need to have current charts when flying.
The marking shows that the publisher does not take any responsibility for the currency or accuracy of the free chart found on internet or in training material.
You can buy sets of current charts and subscribe to updates to always have a current set. Not to promote this here, but one example of company selling charts is Jeppesen. http://ww1.jeppesen.com/documents/aviation/business/ifr-paper-services/glossary-legends.pdf

The really simple answer is that the chart does not contain everything a pilot needs to know to navigate safely. That could be because it is missing features for clarity, is a training tool, or, as is this case for Queenstown, because pilots must have additional certifications in advance. It is very rarely because a chart is out-of-date since why would anyone update a chart that is out of date?
Whatever the reason for the warning, a chart with this prohibition on it is intended to be used to assist a pilot who already knows whatever it is they need to know (as highlighted on this one with the text boxes in the lower left corner), but can not be used safely by anybody who does not already know how to navigate here.

http://www.aip.net.nz/pdf/NZQN_43.1_43.2.pdf
or
http://www.aip.net.nz/pdf/NZQN_45.3_45.4.pdf (also RNAV, but RNAV GNSS, not RNP)
is the type of the approach. The level of details of the map, for example, is exactly the same.
One needs special equipment and a special approval for this approach and cannot just fly it according to the map or select it in a normal Garmin.
The plate misses something important and it is NOT the details of the map. These are the actual minima to be used for the approach (I do not get what other navigation some suggest other than the approach for which the map only exists...). Notice the important notice: Minima figures are indicative only. See CAANZ RNP-AR operator approval for specific procedure minima.
So this approach plate is not enough, more information is needed to properly perform the approach. Not to do other unspecified navigation, no-one would do that, but to fly the approach (or the associated missed approach procedure).

In addition to the other excellent answers, because the publisher expects to be compensated for creating the charts. In other words, they don't want you downloading free stuff, they want to sell you approach plates needed for actual flight. They put this tag on any print or electronic version promulgated for training or general reference.
Right, in addition the publisher is not the CAA itself, but a private company Aeropath, owned by Airways New Zealand, the national ANSP. They have obviously an agreement.

The simple answer is that the chart is or will become outdated. As a pilot you need to have current charts when flying.
The marking shows that the publisher does not take any responsibility for the currency or accuracy of the free chart found on internet or in training material.
You can buy sets of current charts and subscribe to updates to always have a current set. Not to promote this here, but one example of company selling charts is Jeppesen. http://ww1.jeppesen.com/documents/aviation/business/ifr-paper-services/glossary-legends.pdf

The really simple answer is that the chart does not contain everything a pilot needs to know to navigate safely. That could be because it is missing features for clarity, is a training tool, or, as is this case for Queenstown, because pilots must have additional certifications in advance. It is very rarely because a chart is out-of-date since why would anyone update a chart that is out of date?
Whatever the reason for the warning, a chart with this prohibition on it is intended to be used to assist a pilot who already knows whatever it is they need to know (as highlighted on this one with the text boxes in the lower left corner), but can not be used safely by anybody who does not already know how to navigate here.

I suspect these notices appear on the online versions of charts, because the online versions are not guaranteed accurate. The notice probably doesn't appear on the paper version.

Can't say authoritatively as I'm not familiar with NZ rules but in the US, IFR charts are published every 28 days, thus any chart older than that would be 'Not for navigation'. This one was effective 9 Nov 17. Also, redaining the NZ AIP web site disclaimer, the charts are for 'personal use'. This approach is restricted in that it requires GE Aviation approval as well as CANNZ RNP-AR approval. Basically, this is a PBN RNAV approach for airliners with a GE Aviation FMS. So there's no real reason to keep a valid copy on the web site since most of the public can't use it.

It means that you shouldn't use it for navigation.
