The previous dual winner of the Dunedin Cup was Great Sensation in 1961 and '62.
The only other dual winners of the race in the past 100 years are Rorke's Drift (1916 and '19) and Lord Elgin (1946 and '49).
Borninthestates, who also won in 2008, mastered 59kg, the biggest weight carried by a Dunedin Cup winner since Show Gate carried 60.5kg in 1976.
Show Gate carried 12.5kg above the minimum.
Borninthestates carried 6kg.
Show Gate travelled to Washdyke the next day and won the Timaru Cup.
Borninthestates, an 8yr-old gelding, is the oldest horse to win a Dunedin Cup since Bouillon won at the same age in 1991.
Borninthestates was fully extended to hold out Trilogy by a head with a head to Biman.
The favourite, King Montrose, dropped out from the 350m to finish last.
His rider, KC Walters, could offer no explanation for the failure of King Montrose and the horse was given an all clear after a veterinary examination.
It was the 16th win for Borninthestates, owned in Christchurch by Graeme Earnshaw, Maurice and Sandra Fairbairn, Brent Laming, Christine Lindsay and trainer Michael Pitman.
The $28,125 first prize took his stake earnings to $395,650.
He has won nine cup races and the Kumara Nuggets, heading off Bruce Almighty, who has won seven cups.
Borninthestates has also won the Invercargill Cup (2010), Queenstown Cup at Cromwell (2008, '10), Greymouth Cup (2008, '09), Riverton Cup (2008) and Waikouaiti Cup (2008).
He will attempt to repeat his Invercargill Cup win on Saturday week.
Hold It Harvey joins A Gordon For Me (1991 '92), The Fantasy (1980 '81) and Grey Way (1976 '77) as a dual winner of the White Robe Lodge Handicap in 38 runnings of the race.
Hold It Harvey, trained by Terri Rae for Matt Shepherd, had not won a race since his success last year under the same weight, 58.5kg.
He won in similar style, dropping out the rear of a 13-horse field early and powering home to win decisively by half a length from Inferno. Jamie Bullard, who has ridden Hold It Harvey in both his wins, has also won the White Robe Handicap on Volronamo (2004), and Jack Be Nimble (2005).
