Roof replacement compliance issue

We have a builder replacing parts of our 1970's roof. A 'change of pitch' flashing between a 45degree and 10 degree roof has been fixed 25mm from the bottom.

NZ Roofing code of practice clearly has an example of this flashing requiring a perlin at the top of the flashing so that fixing through the corrugate does not penetrate the flashing and also Eliminates stresses placed on that flashing by hard fixing two separate roofing areas.

Our builder is claiming that because he has replaced the roofing elements with the same materials and fixed them in the same place then following this roofing practice is not required.

We had the roof checked by another roofer, who said he would have failed his exam had he installed this element that way.

We want feedback and confirmation that our belief is that regardless of the work being done by a building professional they must apply current building standards when doing their job. Sometime this necessitates some extra work. Surely we should be following best practice to improve weather tightness.

This builder is lining up to have a date at the disputes tribunal.
