John and Tina Bakker Pottery bakers dish

This is a bit of a mystery as i can't track this pottery down.
There was one mention of the patterned pottery bakers dish being "Orewa Gerrand Pottery" on a google search.

However the makers mark looks like JB to me?
On Friday i bought a small cup and thought the maker mark looked familar and comparing it to the baker dish , to me it looks the same.
But who made them? Was it Orewa Gerrand or someone else? Can anyone help please?

This is the work and mark of John and Tina Bakker
