"He was a visionary and loved this country."
With Lani, Earl continued to lead the Scenic Hotel Group until his death.
"He will be greatly missed by all of us. Today was a very peaceful and loving end to a remarkable story," Lani Hagaman said.
"There will never be another Earl. I loved him immensely."
Earl and Lani Hagaman started defamation proceedings against Andrew Little in June last year after the Labour leader made remarks about donations to the National Party.
Little claimed a partial victory after a jury in the High Court at Wellington in April found he had not defamed Lani Hagaman in the court case in which the Hagamans were suing for up to $2.3 million.
The jury was unable to agree on whether four of the six instances claimed as defamatory by her husband, Earl Hagaman, were defamatory. In the one instance the jury decided was defamatory of Earl Hagaman, it was unable to agree whether Little could apply his defence of "qualified privilege" so could not enter a decision.
Lani Hagaman said last month that she will continue to pursue a defamation case against Little on behalf of her husband, including going ahead with a retrial.
In 2009 Earl was awarded the inaugural New Zealand Hotel Industry Achievement Award, and in 2014 he was made a Companion of the New Zealand Order of Merit in recognition of his services to business, tourism and philanthropy.
