Seed to Home Q&A
The problem and the idea
What is Seed to Home? A way for Northland whānau to build a warm, healthy home on their own land by growing hemp on it first. Grow the hemp, process it close to home, sell part of the harvest, keep the rest to build hempcrete walls on a timber frame.
Why hemp, specifically? A lot of whānau have land but can't afford to build on it, and too many are stuck in cold, damp housing that's bad for their health. Hemp grows fast, needs little input, and turns into a building material (hempcrete) that's warm, breathable and resists mould, fire, rot and pests, so the same crop that earns income on the land can also become the walls of the house.
Why Northland, why now? This is where the land, the need and the whānau connections already are. Banks generally won't lend against multiply owned whānau land, and conventional building costs put a home out of reach even when the land is already owned, Seed to Home is built specifically to get around both of those barriers.
Will it actually work?
Has hemp actually grown around here before? Yes, hemp has already been grown successfully around Taitokerau over the last decade. We've got ground prepped and leases in place on three sites, with seed going in the ground this season, backed by soil test results.
Is growing hemp tightly regulated, do you need a special licence? Not anymore. The old licensing system (the Misuse of Drugs Industrial Hemp Regulations 2006) was revoked on 28 May 2026. Growing industrial hemp (THC under 1%) is now notification-based rather than licensed, meaning we notify NZ Police and MPI with the specific site details before planting, but there's no licence to apply for or wait on.
Is hempcrete actually a proven building material, or experimental? Proven. It's been used in builds overseas for decades, with real durability research behind it (CSIRO, Monash). A monitored UK social-housing build showed far lower heating costs and a fraction of the embodied carbon of a brick home.
Can a hemp home actually be legally built and consented in New Zealand? Yes, under the Building Code's Alternative Solution pathway, and there are already examples of hemp building in Northland and elsewhere in NZ.
Will it actually be cheaper to build this way? That's the one piece I’m still firming up with real numbers. I have a detailed, line-by-line cost comparison showing a meaningful saving over a conventional build, but the conventional side of that comparison is currently built from industry-standard estimates rather than actual local quotes.
What's the local processing machine for? It turns raw hemp stalk into the hurd (woody core) used in hempcrete. That's what this PledgeMe campaign is funding, proving local processing works, not just growing and shipping the raw crop elsewhere.
Supporting the campaign
What exactly does my pledge fund? The processing machine (the Hansa F3) that turns raw hemp stalk into building-grade material, plus the trial run that proves local processing actually works.
When and how would my card actually be charged? Only if the campaign hits its $9,500 target by the closing date. If it does, PledgeMe charges your card at that point, or bank account if you choose that option when you pledge, not when you first pledge. If it doesn't reach target, nothing is charged and no pledge goes through.
I'd rather not pledge through the PledgeMe website, is there another way? Yes. If you'd like to support this but would rather not go through the platform (card details, account sign-up, and so on), get in touch at kiaora@taitokerauhemp.co.nz and we'll sort a direct way, cash or an internet transfer.
What happens if the campaign doesn't reach its target? It's all-or-nothing: the target is $9,500, and if the campaign doesn't reach that, every pledge is refunded in full and nothing is kept.
Why don't you just get a loan or pay for it yourself? A few reasons. It's part of the model itself, Seed to Home is built on growing first and using crop profits to fund the next stage, not leaning on debt, so borrowing for the very first piece of equipment would undercut the thing I'm trying to prove. A crowdfunded campaign also does something a loan can't, it shows councils, funders and whānau that there's real, visible support behind this, not just me saying so. Keeping early borrowing low matters to my own family too, and I'd rather bring people in as backers than carry that risk alone. Practically, $9,500 spread across a community of supporters is also a lot easier to raise than to personally fund right now, with everything else going into the land and the crop.
I can't pledge money right now, can I still help? Yes, and it genuinely helps: sharing the campaign with people who might back it, or just talking about it, builds the kind of visible support that councils, funders and other whānau notice.
Is this a registered business, a charity, or something else? It's a registered New Zealand business: Taitokerau Hemp Limited, a limited liability company incorporated under the Companies Act 1993, wholly owned by me (Dave Hovell).
What happens next
How long until an actual house gets built? The model is year one: grow and sell the crop; year two: expand and bank a reserve; year three: build, using crop profits plus the hemp grown that season. So the first Seed to Home build is realistically a few years out, not this year. Aside form this Seed to Home model, there are other hempcrete builds in the planning stage for Northland so we will likely see other builds and workshops in 2027.
Do I need to already own land to take part? This pilot is working with whānau who already have land they can't yet build on, but it's not closed off. Planning and preparation for a new intake start in early 2027, with new sites able to start growing next season.
Who's behind this? Dave Hovell, founder of Taitokerau Hemp Ltd.
