Richard and Gloria Morgan were already close but her gift of a kidney has made the Napier couple's bond stronger.
They learned he had a hereditary kidney disease early in their married life, when he was in his late 20s.
Kidney recipients usually have to have a clear bill of health, unless one was gifted. She was unaware she could be a donor until she spoke to another wife-donor five years ago.
"My husband was ineligible to get the kidney from anyone else but me because he also has a cardiac history, so we needed to have it from a family member or friend, but the best match was me."
Living together enhanced their compatibility, lowering the chance of his body rejecting her tissue.
