"Nine and Cordell Jigsaw accept that Mrs Rinehart found the broadcast to be inaccurate.
That was certainly not the intention of Nine or Cordell Jigsaw, and each unreservedly apologises to Mrs Rinehart and her family for any hurt or offence caused by the broadcast and its promotion."
Its understood the program won't be released again on DVD, streamed, or sold overseas.
Mrs Rinehart took legal action for defamation against Nine and Cordell Jigsaw when the series, starring Mandy McElhinney screened in February 2015.
It attracted about 1.3 million viewers, and the second instalment was swiftly edited when Mrs Rinehart won the right to see it the second instalment before it aired.
A statement from Hancock Prospecting - which Mrs Rinehart heads - said the case was "not about money" an Mrs Rinehart was pleased to receive a public apology for "such an inaccurate and distorted mini series".
"Mrs Rinehart and others who truly knew the Hancock family and Mrs Rinehart, were disappointed such an inaccurate and distorted miniseries against their family, family
members who greatly contributed to our country, was aired by Channel Nine, which did not depict the actual people, and is pleased that she has received a public apology," it said.
"This case was not about money. It was about Mrs Rinehart standing up for her deeply loved family members to try to stop the further spreading of unfair and grossly disgraceful falsehoods about her family, especially when certain of her family members are no longer here able to defend themselves.
"This matter was not just about the fundamental right of Mrs Rinehart and her family not to have lies and misrepresentations spread publicly about them, but Mrs Rinehart hopes that this matter will lead to the greater protection of others from such unfair conduct by the media and lead our politicians to activate long overdue reform in this area."
