Several months later she, Sarah, Will's brother Sam and his best friend Adam Williams started the Will To Live, campaign to provide support for young rural people aged 20 to 30 who were feeling desperate and isolated.
That age group has one of the higher suicide rates in New Zealand.
Ms Perriam said her sister had finished Lincoln University for the year and was working on a sheep stud in North Canterbury.
She had Will's black huntaway Jess with her, who who was loving her time on the farm.
Jess is the campaign's mascot.
''Jess has been amazing and has been in television studios and on planes,'' Ms Perriam said.
They launched Will To Live during the Hunterville Huntaway Festival in October.
''There was an amazing turnout,'' she said.
''The number of stories we heard of people travelling to get there was probably the most humbling.
''There was one family who heard about the event the night before, and drove up from Marlborough to be there.
''[A family member] said his brother committed suicide a week after Will did last year.
''They wanted to be there to be part of it.
''It was incredible.''
The campaign was launched by a mass dog ''bark up'' at the event.
She had been surprised and amazed at the response the campaign had received.
They raised more than $18,500 from a Pledgeme page and also received other donations, as well as support from industry groups and companies, including the free use of a Holden Colorado for Elle for a year.
The money will be used for the tour.
