DIRECTOR Martin Byrne hopes the play-off success will help boost McAlpine attendances in Division II next season.
The man who helped save the club from liquidation last year was among 23,000 Town supporters at the Millennium Stadium to see Peter Jackson's side clinch a first promotion since 1995.
With cut-price season tickets on offer until June 11, Mr Byrne said:
"We know that everyone is behind us and, hopefully, crowds will swell again next season from the brilliant numbers we've seen this time.
"There seems to be a bit of belief in Huddersfield Town again.
"It's something I've never doubted because that's why I fought to save this club, but everyone is beaming at the moment and it's just brilliant to see."
Mr Byrne watched the match with Chris Wood, the administrator who ran the club during their darkest hours.
"It has been a long, hard road since that time but all the hard work has paid off and we're up," said Mr Byrne.
"We are basically half way back to where we want to be and I can't tell you how happy I am for everyone.
"It was a marvellous occasion on Monday, a great result and a brilliant reward for everyone concerned.
"I remember speaking to the Mansfield chairman afterwards and he was distraught. I'm just so glad it wasn't us!"
