Interesting update... without delving in there: how much and how fast is the magnetic pole moving from True North?
I know some runways have had to be renamed recently.

I thought the declination went smoothly with latitude, but no:
The isogenic lines (from Wiki)
That'll give you 8 deg difference over NZ, N to S.
Wonder if my iPhone knows this...
