When the ground moves, who moves first?

Told to stay home after the Christchurch earthquakes, Sam Johnson asked students to bring a shovel. 11,000 turned up. Fifteen years and 20+ disaster responses later, his talks leave people ready to act before they're asked, bring others with them, and lead when everything shifts.

Keynotes

Four talks. One true story.

Each talk starts from the same moment in Christchurch and is shaped around what you want people to leave with. Each runs 20 to 50 minutes, with room for questions or a workshop.

Grab a Shovel

Why the people who change things rarely wait for permission, and how anyone in your audience can become one of them on Monday morning.

  • Start with the smallest useful thing. How one Facebook event became a national movement.
  • Turn frustration into a plan. Sam's five-step cycle: vision, plan, promote, do, review.
  • Make it easy for others to join. Momentum comes from giving people a clear first task.

What changes: people leave with one thing they will start this week, and the confidence to start it without waiting to be asked.

When the Ground Moves

What ten years of responses to earthquakes, floods, fires, a terror attack and a pandemic teach about leading when nothing is certain, and building resilience before it's needed.

  • Know when to move, and when to wait. Deciding whether to respond matters as much as moving fast. The calls that mattered in Christchurch, through COVID-19 and in the Nelson floods.
  • Give people a way to help. After a disaster, helping someone else is how people get their footing back.
  • Ask forgiveness, not permission. And be clear about who carries the risk when you do.

What changes: teams leave clearer on how they will decide and act when the next disruption hits, and on who they need beside them before it does.

Grounded in “A shovel or a shopping cart”, Sam's co-authored study of ten years of SVA disaster response, published in Natural Hazards (2021).

Leadership & cultureChange

Build Your Own Army

How to get people moving in the same direction without a budget, a title or a burning platform, by building movements for impact, not empires for ego.

  • Share the risk to share the load. Culture grows when teams carry real responsibility.
  • Give permission to act. Remove the gatekeeping that stops good people moving.
  • Organise for scale. How a core team of 15 coordinated thousands each day.
  • Recognise what you want more of. Across the SVA in 2025, hours volunteered rose almost in step with awards given.

What changes: leaders leave knowing how to hand over real responsibility, and why that builds a stronger culture than control does.

Leaders of Right Now

Young people aren't the leaders of tomorrow. Given trust and a real task, they lead now. What that means for how you hire, manage and keep them.

  • Trust plus a real task. The formula behind the SVA Service Award, now running in 240 schools.
  • Responsibility builds people. In South Australia, 80% of SVA students reported more confidence and 70% said their mental health improved.
  • The barriers are structural, not motivational. Once they're in, students from disadvantaged schools volunteer just as consistently. Remove the barriers, not the expectations.

What changes: managers leave with practical ways to give young people real responsibility, and to keep them.

The story

From a student with a shovel to an Officer of the Order of Merit

In 2010 and 2011, earthquakes broke Christchurch. Sam Johnson was a university student being told, like everyone else his age, to stay home and keep out of the way. He set up a Facebook event instead and asked students to bring a shovel.

More than 11,000 came. The Student Volunteer Army shifted tonnes of liquefaction silt from the streets and homes of a city in shock, run by a core team of 15 who learned to coordinate thousands of strangers every day.

Leadership is a shovel, not a slogan.

That moment became fifteen years of work on one question: what happens when ordinary people are trusted with real responsibility? As SVA Chief Executive, Sam led more than 20 disaster responses, from floods and fires to grocery deliveries for vulnerable people during the COVID-19 lockdowns. He took the model abroad to Japan and Nepal and worked with the UN Office for Disaster Risk Reduction on youth involvement in the Sendai Framework.

Today Sam is Projects Director and Governance Lead at STILL. He chairs the Student Volunteer Army, Kings Plant Barn and Humphries Landscaping, is a director of Consult Recruitment and Hulbert House, and is a founding trustee of The King's Trust Aotearoa New Zealand and Paererewā, the 1,000 Year Bench Project. In 2026 he was appointed an Officer of the New Zealand Order of Merit for services to the community and youth.
