Road closures missing (NZ)

We’ve had some weather events that have resulting in flooding closing some roads around the country. These closures are reflected in other navigation apps but it doesn’t seem to be reflected in the ABRP routing. Worst case is it could result in being stranded in shorter-range vehicles. Examples are attached.
