Zones in Tanzania

Hi,

Looking at Tanzania relation on OSM, I see that it has several subarea linking to Zones - like Northern Zone. Looking at wikipedia, the first administrative subdivision seems to be 22 Regions, not 7 Zones.

So, here is the question: are these seven Tanzanian Zones official?

For a bit of context: I need stable OSM relations to generate smaller extracts for Osmose QA, as Tanzania is getting a bit too big now.

Thanks,
Jocelyn

I wasn’t able to add links to the two relations, but here they are:

The relation has been created by user LLAQWA who is still active on OSM. Perhaps he can answer your question

Good idea, I’ve sent a message to LLAQWA.
