"All the finalists were stunning on the night but across the three days of competition the standard from every singer was very impressive.
"It was a wonderful night to celebrate not only 20 years of the modern Aria, but also 67 years of competition singing in Rotorua."
And the Aria competition could only continue to improve, Mr Edward said.
"Many in the industry here and overseas are now comparing this competition to the very best internationally.
"It is the key reason we are having our young singers achieving with a high level of distinction with their peers internationally.
"The Aria succeeds on three levels - the singers' performance is lifted when accompanied by a full orchestra - the Auckland Philharmonia - and Chapman Tripp opera chorus, plus the high-quality judging, and tertiary institutions are now recognising the competition is crucial for the development of music students.
"Surely it can't get any better but I believe it will."
The 10 New Zealand Aria finalists performing last night were: Christian Thurston, Daniela-Rosa Capeda, Maia Vegar, Amina Edris, James Ioelu, Eliza Boom, Marlena Devoe, Oriana Kershaw, Edward Laurenson and Elizabeth Hanna.
Te Puia Maori Song Aria winner Taunoa Filimoehala also performed with second-placed Te Waikamihi Korohina-Ormsby, and third placed Stella Maris, both of Rotorua.
Full results of the New Zealand Aria finals, and weekend finals will appear in the Rotorua Daily Post tomorrow.
