Looking for Long Lost Cousins IN New Zealand

I am looking for relatives that emigrated during WW1 or after WW!
All I know is that thier names are Ju, short for Jude,June or Julia and Bob. They started working on the Railways then ended up having a sheep farm. I have lots of photos taken between possibly 1940's - 1960's
We believe that they may have been in the Wanganui, Marton way. as Photographers are printed on back of Photos.
I have attached a Photos for you to look at
Regards
Angie
