Broom belted 30 off his last nine balls, including three of his eight sixes off successive balls in the penultimate over. Dutch international ten Doeschate helped him blaze 128 off eight overs for the fourth wicket.
"The way Derek played was pretty special and 'Tendo' stepped up a notch, which he usually does," Broom said.
Broom has been in the sub-continent with New Zealand A for several weeks, and admitted the preparation had done him plenty of good.
"I haven't scored too many runs but it's nice to prepare yourself in these conditions."
Otago's is the second best successive winning run in T20 and coach Vaughn Johnson conceded their days of "flying under the radar" are probably gone.
They play South Africa's Lions in Jaipur on Sunday night, folowed by the Rajasthan Royals early on Wednesday (NZT).
"We're probably going to be targeted now. The next two games we have to up the intensity because they're quality sides," Johnson said."
The Royals lead the group on eight points, Otago have six - and a thumping run rate - with Mumbai, Lions and Perth on two.
