I am hoping somebody could assist me in finding out some information regarding my Paternal Grandfather who died in 1974.

He left New Zealand between 1946 and 1952 and arrived in the UK.
He married my Grandmother in Kensington , London in Sep 1952 and never returned to New Zealand i believe before his death in 1974 in the UK.
I have been trying to find some travel documents or migration documents for him to assertain a date he left New Zealand to the UK and the reasons why.
Rumour in the family is he was a laundid person due to something that happened in New Zealand.Wether this is true or not i don't know.
