Mr Munro's portrait will hang in London's Imperial War Museum with those of Canadian Flight Sergeant Fred Sutherland in Canada and Bristol-based Squadron Leader Johnny Johnson.
Of the 144 young men who took off from RAF Scampton in East Midlands in May 1943, 56 failed to return, all but three of them sacrificing their lives.
Mr Munro's Lancaster was hit by flak over the Netherlands and with all communications knocked out, the decision was made to turn back to base.
"As a result of that, I feel as though I can't be part of the glory of having been part of that successful raid ... that's the downside," he said yesterday.
Mr Stone begged to differ.
"We had this chat during the week and Les took responsibility for the safety of his crew ... that takes a remarkable amount of bravery."
The pair have bonded since Mr Munro collected Mr Stone from Tauranga Airport last Sunday, the Kiwi host showing his guest around town and sharing stories over dinner.
Mr Munro still felt flattered about the experience when he spoke to the Weekend Herald yesterday, describing it as "something I never ever dreamed would happen". Mr Stone insisted the pleasure was all his.
"Every day now I read the obituaries of heroic nonagenarians and reflect on what a splendid generation we are losing," he said."If I can help preserve the memory of another one of them, then I should."
