The winner previously excelled in the preliminary Ubungo area before progressing to win the Miss Kinondoni beauty pageantry thereafter.
The Maasai young lady responded well to questions posed by Jokate Mwegelo. She looked highly confident to answer questions in English language with high degree fluency that left most of the spectators in bewilderment.
“What incident that actually made you happy throughout your life so far”, that was the question Diana responded well.
The winner edged another contestant from Dodoma, Anna Nitwa who was a pre-event favourite but she lacked the courage to respond with confidence.
Ilala contestant Juulitha Kabethe also fauled to respond well to Mwegelo’s questions.
The five top-placed contestants included Juulitha, Anna, Grace Malikita and Mary Peter of Tabata, Ilala and Mwanza respectively.
Peter was runners-up of the event after edging Grace to the third place in the final standings.
Diana was presented with a brand new Toyota IST saloon car by the guest of honour who happened to be the Deputy Minister for Information, Culture, Arts and Sports, Anastazia Mabula ( Ilemela MP).
The guest of honour hailed the organisers for staging the event and congratulated Lino Agency International under its director Hashim Lundenga.
Outgoing Miss Tanzania Liliani Kamazima, crowned Diana amid cheers from the spectators who turned out in huge numbers.
Former Miss Tanzania who also attended the function include Wema Sepetu, Jokate and Hoyce Temu (Miss Tanzania 1999).
Diana will represent Tanzania in the 'Miss World 2016' expected to be staged in the United States in December.
