"This is not about forgetting. We will never forget but it is about forgiving," Ms Edwards said.
The whanau realised Wills had not set off on November 5, 2011, to harm anyone, she said, and that "many factors" had worked against him and Mr Cobb on the fateful day her partner lost his life.
Addressing Wills as he stood in the dock, Ms Edwards said: "I offer my forgiveness and the forgiveness of my family."
The sentencing yesterday came in the wake of a Restorative Justice conference and an offer by Wills that was described by Judge Hastings as being a "generous offer" driven by genuine remorse.
This included emotional harm payments of $5000 cash immediately available after sentencing, a further $10,000 cash payments a year later and another $10,000 to be paid into a trust fund for the three children - that payment to be made by July 31.
Wills also promised to supply frozen meat and produce to Ms Edwards and the family on an on-going basis.
Judge Hastings made a personal statement from the bench.
He said Ms Edwards had made a comment that she and Wills "came from different worlds".
"But they are not so different you can't recognise the good in each other and I can see you are both good people.
"Many victim-impact statements read to courts are fuelled by anger, which prohibits healing, but Ms Edwards, your statement rises above, from a basis of sorrow which embraces forgiveness.
"Both of you have shown a generosity of spirit, so leave this courtroom and live your lives well," Judge Hastings said.
Solicitor Mike Antunovich appeared for Wills and said the Greytown man's letter of apology, explanation and reparation offer spoke for themselves.
Wills had made a "serious misjudgment based on overconfidence" that had unfortunately claimed the life of Mr Cobb.
Mr Cobb died when a laden trailer towed by Wills' car hit the guardrail of the bridge and jack-knifed into the path of Mr Cobb's motorcycle.
