Campbell said she knew others shared her frustration at the wall being closed and, after setting up the club, it signed a memorandum of understanding with Sport Northland and the wall is back in action.
She initially set up a Facebook page to gauge support and with almost 500 followers decided to take things a step further about a year ago.
''We held an open day at Sport Northland for anybody who may be interested in the wall reopening and we had over 30 people turn up. It was a good response and showed there was a lot of interest,'' she said.
''So we set up the club with a seven-member board of people, with most of them experienced and qualified climbers. We've got a national champion up here (Monique Gray) who has had to go to Auckland once a week to practice on their wall there, and while Whangārei Boys' High School has a small indoor wall, we really need this bigger one so our climbers have a good wall to climb on.
''And who knows how many more national champions we may have up here who have never had the chance to climb on this wall.''
With sport climbing now an Olympic event, there is major worldwide interest in the sport, but most countries have climbing training.
''I know my kids are so pleased to have it open and I'm so excited to have it open for them and others who want to climb.
"Kids love to climb and this is an ideal place for them to do it safely but with a good challenge to suit all levels of skills.''
Initially, the club will climb at the wall on Thursday evenings, but Campbell said they hope to also be open on Tuesday evenings and, if there's demand, on Sunday afternoons, too.
''We don't mind anybody wanting to come along or have a go, and hopefully, we can find another national or Olympic champion from Northland.''
