A drought was declared in Hawke's Bay in March and despite recent rain, conditions remain tough and feed levels are low across the region. Renton decided to reach out to his famous footy mates and asked them to record positive messages to keep farmers' spirits up.
Listen below:
He was pleased with the response.
"I just messaged them and to their credit - and I'm really grateful for this - they just reached out straight away and they just said 'yeah, no worries ... I just want to help any way I can and as much as I can' ".
"I'm incredibly grateful for their time and also for the message - because the messages are really genuine and really heartfelt".
So far All Blacks captain Sam Cane has recorded a message which had been well received - and there were more videos to come, Renton said.
"There are other All Blacks [that] I've reached out to and they're incredibly busy, so it is pretty special that first they even considered doing this, and secondly, are thinking of Hawke's Bay farmers".
Renton hoped his videos would inspire farmers to do "a good day's work", knowing that others understood they were going through tough times.
"It's not about me or anything like that. It's really just to show support for these farmers".
"Keep doing that darn good job, keep waking up, keep continuing [to farm] because you're the real backbone of New Zealand".
Also in today's interview: Renton talked about whether he would return to the family farm after finishing his accounting, finance and psychology degree at Canterbury University.
