The 93-year-old was the oldest former pupil to join in the festivities during the weekend and although only one original building remained from her time at the school, she was struck by its familiarity.
''When I came back, I thought the old school hall is exactly the same as when I was here,'' she said.
''The same windows and everything.''
She attended the school between 1926 and 1935 and the sprightly nonagenarian was excited by the opportunity to come back to the school where she enjoyed being a pupil.
''My four sons, this was the only school they went to, and my two grandsons, and I had a sister who went here,'' she said.
''My sister made me late for school and because I was late the headmaster gave me three straps on the hand - all because I was five minutes late.''
Sisters May Teasdale (84) and Eldora Gilbert (79) also recounted their memories of attending the school in the mid to late-40s.
''I can just about imagine how [the school's buildings] were,'' Mrs Teasdale said surveying the school's grounds.
''The hall is the only thing that was left.
''We had a chap they called the band, he had a drum and he banged it as we walked into the school. We had to march and walk in an orderly fashion.''
Her sister recalled being served milk warmed by the sun and the play breaks.
''We couldn't stay inside for breaks,'' she said.
''We had to go out, no matter what the weather.''
Mornington School 150th jubilee committee chairman Clark Bragg said about 320 people had taken part in the celebrations, exceeding expectations.
''It's a really, really good turnout. We are really pleased.''
More than 100 former pupils joined the current pupils for assembly on Friday afternoon and Dunedin City councillor Neville Peat and former police commissioner Howard Broad spoke during the welcome to the school on Saturday.
''It's been really good and they are really enjoying themselves,'' Mr Bragg said of the former and current pupils.
''Reunions are an amazing phenomenon.''
The jubilee celebrations concluded with a memorial service and barbecue yesterday.
