Another Wairarapa SHB member, Masterton farmer Vaughan Marfell, was one of the star performers with dog Torque, winning both the North Island and New Zealand straight hunt titles.
Prouting was unable to take his winning form into his national title runoff on Saturday and finished fifth, with the zig zag title going to Dave Stuart and Gus, of Rangiwahia.
Two other Southern Hawke's Bay farmers reached the national runoffs, with Dannevirke club member Gerard Brown and Tempo third in the zig zag hunt and Brent Matthews, of Makotuku, fifth in the short head and yard in which Eion Herbert, of Wakefield, completed a North Island and New Zealand titles double with Storm, blocking a North Island cleansweep of the titles at last week's championships and the South Island championships near Balclutha last month.
The long head was Bruce's first New Zealand championships title. He had twice previously been runner-up, including in 2009 at home club Te Aute which stages the North Island championships next year, when the national championships will be held with the South Island championships in Marlborough-Nelson.
He had, however, won a North Island long head title at Ohaeawai in Northland in 2012 with Trump, Cheat was Hawke's Bay's top heading dog in 2015 and jointly this year with Dave Wallace's Blue, and in April Cheat won the Hawke's Bay Centre championships short head and yard title with Susan.
Prouting's win was his first at either Island or New Zealand championships level, but Vince had reached the zig zag runoff last year, and has won the Wairarapa SHB top huntaway title.
With David Shield, of Dannevirke, having won the South Island long head title last month, the Wairarapa SHB centre ended with four of the 12 titles at the major events.
