Hurricanes coach Chris Boyd is heading overseas at the end of the Super Rugby season citing a lack of options in New Zealand as a major reason.
Boyd led the Hurricanes to their first-ever title in 2016, following stints with the Lions and New Zealand under-20s, but 2018 will be his fourth and final year with the Wellington franchise.
Boyd said he it was a tough decision to leave and in a 'perfect world he would've stayed at the Hurricanes for 10 years and retired.
The lack of opportunities led him to make the tough decision to head north.
"Once you get to Super Rugby head coach in New Zealand there is really nowhere to go," said Boyd.
"I think it's an issue potentially for New Zealand Rugby that there's a lot of experience and intellectual property that ends up going overseas.
"There is really nowhere to go after that in New Zealand and so it's a great opportunity, I am looking forward to it and being involved in a different competition.
"The Northern Hemisphere is only going to continue and get stronger and I think that is an issue for down here."
Boyd said his move overseas isn't motivated by the idea of gaining experience and returning to New Zealand to try and get a job with the All Blacks as he doesn't know what the future holds.
"There is no motivation from me to head overseas to get experience to come back and look for an All Blacks job.
"For it is about when the opportunity is right to do it and if it means it's the right thing to give it away in terms of full-time coaching after my stint in Northampton that is what will happen.
"If you ask me where I'll be in three years' time, I actually have no idea."
The Saints were one of a number of clubs in the northern hemisphere who were chasing Boyd's services which included the Wales national team who are looking to replace fellow Kiwi Warren Gatland at the end of the 2019 Rugby World Cup.
Hurricanes assistant coach John Plumtree is the early favourite to replace Boyd as head coach of the Wellington franchise in 2019.
