Not sure what mount they use in NZ, but if you are looking to mount a smartphone to a foot-stretcher, look at the modular mounts used on motorcycles and bikes. Two challenges for rowing iphone mounts are: to be quite secure to avoid dropping the phone in the water and to enable adjustment to any angle to make the screen readable in a wide range of light intensities and directions. Here's what I found worked for my 1x (though there are more options now than 4 years ago when I ordered these parts).

You can attach this widget with a bolt to your foot-stretcher to provide a base for connector and phone holder:

...then use this connector which rotates in all directions:

...and this widget to hold your phone (also moves in all directions on a ball joint):
