"It's very tough over here, both physically and mentally, and I've handled it, but at the same time I've been homesick.
"Going home is something I've thought long and hard about and I've had advice from a lot of friends.
"Chris [Waller] has been pushing for me to stay, but my heart is set on going home.
"It wasn't an easy decision to make, but it's a decision I had to make and the right time is at the end of the season. It could be the right or wrong decision, but that's a chance I am prepared to take.
"Besides, when I first came over here, it was for three months, and I've ended up staying just on 15 months."
Weatherley was originally apprenticed in New Zealand to Lance O'Sullivan, but when he returns, he will be indentured to his father Darryn Weatherley, who trains a small team and pre-trains at Matamata.
"I've still got eight or nine months of my apprenticeship to complete and I'm signing up with Dad," he said. "I want to be able to focus on riding all over the country. I will be riding trackwork at Matamata, but plan to go over to Cambridge a couple of days a week. I will be out to get the best rides I can, so I want to be free to ride wherever possible."
Weatherley has engaged Aidan Rodley as his agent and will resume his New Zealand career on the first day of the Grand National meeting, where his mounts already include Elfee for Michael and Matthew Pitman in the Group 3 Winter Cup (1600m).
"She should be a good chance and Michael [Pitman] said he has a couple of other nice horses for me to ride," Weatherley said.
"He said he's got the best team he's ever had and I'm really looking forward to riding for him again.
"I've rung and talked to him often since I've been in Sydney and he's inspired me."
Weatherley's biggest success, his first Group 1 win, came on the Pitman-trained Enzo's Lad in the 2018 Telegraph (1200m) at Trentham.
Weatherley was champion New Zealand apprentice in his first full year with 67 wins, then again won the title with 66 wins in 2016-17 before heading to Sydney.
He has made fleeting trips back to ride in New Zealand and was part of the Young Guns team which won the World Cup series at Ellerslie last December.
One of those trips home also resulted in a win on Charles Road at Hastings last September, taking his New Zealand tally to 142.
With a total of 187 wins on the board, Weatherley obviously has no claim in New Zealand, having outridden it before he transferred to Waller, but being able to ride at 54kg should broaden his opportunities.
"My long range goal is to try and win a jockeys' premiership and I'll be travelling to as many meetings as I can," he said.
