Thanks for noticing that. The admin boundary is also an abandoned railway line and I didn't check as thoroughly as I should - the mapping in this area is quite poor in parts. Now all fixed I hope

Yes, please revert. I have all the GPX tracks conserved and tagged waypoints so I can reinstate the other changes when I am next in the Uk

I have been in some of the more inaccesible parts of . New Zealand since Chritsmas and have only now returned to e-mail etc. It was certainly not my intention to delete parts of the relationship - my intention was to order it and fill in recent changes. I was doing a significant chunck of work using JOSM but abandoned that when it became clear that time was against me. I had though to abandon and delete the changes. I subsequently made some minor changes in Diamond Harbour NZ. I guess it is conceivable that previous changes were uploaded at the same time. I any, please accept my aopolgies - wholly unintended and I will give myself much more time before updating large relations like this. Thanks for reverting the changes. I will check back through my tracks on my return to the UK to ensure that all minor route changes have been retained.

Yes, apologies for that - it was probably getting late. Now corrected. It was a highway footpath that diverted away from the highway and then crossed a minor road. Now joined to the minor road and tagged more appropriately
