But even a win last season would not have seen the Pirates go up as their ground does not meet Premiership standards.
"Chris Stirling has been here three years and at the moment we're looking at Chris taking a bit of a sabbatical while we see what happens with the stadium," chairman Dickie Evans told
BBC Radio Cornwall
"When I last spoke to him he was quite happy to take the call and come back when necessary from New Zealand.
"He does want to coach a top class club and the Pirates is his main opportunity.

Replaced Mark Hewitt as boss
Led Pirates to the 2010-11 Championship play-off final
"In New Zealand most of the coaches are ex-All Blacks so Chris doesn't have a lot of opportunities at the top level.
"If he could end up coaching the Pirates in the Premiership that'd be Chris's dream and we'll keep the opportunity open for him," Evans added.
Stirling played over 250 matches in his homeland and represented Wellington's 'B' side as a winger and centre.
He also coached at Wellington and NPC club Buller.
Stirling's family are also based in New Zealand, with his wife, three daughters and grandchild all planning to move back to his homeland during the summer of 2012.
But despite that Stirling says he will not desert the Pirates.
"I am committed and I will be coming back.
"I will go to New Zealand for 12 months and do some work in rugby development, but that's not what I want to be doing. I want to be working at the highest level.
"I've always been loyal to the Pirates and always will be.
"If I say to Dickie and the Pirates that I'll be back then I definitely will be," he added.
