"I have seen vast improvements in standards and levels of both Northland players and teams over the last few years, culminating with Northland FC now taking over the Talent Development side in the region.
"All of this would have been impossible without the leadership, continuous drive and support from Dave. He is a true legend of the game."
NFC chairman Mike Davies said Alabaster's work in the youth game is a big part of his legacy in Northland football.
"The Northland Youth development programme is a testament to Dave's dedication to the game," he said.
"This award is a small thank you to Dave for the countless hours of his time ensuring its success.
"We are excited by the challenge of continuing the fine work Dave has done before us and maintaining the standards he has set for elite football development in Northland."
Alabaster joins Chas Flower (NFC Chairman 2004-2016) as the second life member of NFC.
