In New Zealand, the terms landscaper and landscape architect are often used interchangeably, but they refer to quite different professionals with different training, skills, and roles. Understanding the distinction helps you hire the right person for your project — and can save you time, money, and headaches down the track.
What Does a Landscaper Do?
A landscaper (sometimes called a landscape contractor or gardener) is a tradesperson who physically builds and installs outdoor spaces. Their work is hands-on and practical, and typically includes:
- Planting trees, shrubs, and garden beds
- Laying turf, paving, decking, and pathways
- Installing retaining walls, fences, and garden edging
- Irrigation and drainage systems
- Soil preparation and mulching
- Ongoing garden maintenance
Landscapers in NZ do not need a specific government licence to operate, though many hold trade qualifications such as a New Zealand Certificate in Horticulture or have completed apprenticeships. Quality landscapers are often members of industry bodies like Horticulture New Zealand or the Registered Master Landscapers association, which can give you added confidence in their workmanship.
Important note: Some landscaping work — such as connecting irrigation to your water supply, installing outdoor lighting, or building structures that require a building consent — will involve restricted work that must be carried out by licensed professionals. Plumbing connections must be done by a licensed plumber registered with the Plumbers Gasfitters & Drainlayers Board, and any electrical work must be completed by a registered electrician under the Electrical Workers Registration Board.
What Does a Landscape Architect Do?
A landscape architect is a qualified design professional, typically holding a Bachelor's or Master's degree in Landscape Architecture from a recognised university. In NZ, landscape architects may be registered with the New Zealand Institute of Landscape Architects (NZILA), which requires meeting education and experience standards.
Landscape architects focus on the planning, design, and management of outdoor environments — from private residential gardens to large-scale public parks, urban streetscapes, and environmental restoration projects. Their services often include:
- Site analysis and concept design
- Detailed construction drawings and specifications
- Resource consent and building consent documentation
- Coordination with engineers, architects, and councils
- Environmental impact assessments
- Project management and contractor oversight
Because landscape architects produce formal design documentation, they are well-suited to complex or large-scale projects where council approvals, structural elements, or significant earthworks are involved.
Key Differences at a Glance
| Landscaper | Landscape Architect | |
|---|---|---|
| Primary role | Physical installation & maintenance | Design, planning & documentation |
| Qualifications | Trade cert / horticulture diploma | University degree (BLA or MLA) |
| Licensing | Not government-licensed | May be NZILA registered |
| Typical projects | Residential gardens, planting, paving | Complex design, consents, large-scale |
| Fees | Hourly or project rate | Design fees (hourly or % of project) |
Do You Need a Building Consent for Landscaping?
This is a common question. Many landscaping projects fall under Schedule 1 exemptions of the Building Act 2004, meaning they don't require a building consent — for example, small garden sheds, low retaining walls (the exempt height threshold depends on factors such as whether the wall supports a surcharge — check with your local council for the specific criteria), and basic decks. However, the rules depend on your specific situation, including your local council's requirements and the proximity of structures to boundaries or other buildings.
Always check with your local council before starting work. MBIE Building Performance has helpful guidance on what work requires consent, and your council's building department can confirm what applies to your property.
Which One Do You Need?
Here's a simple way to think about it:
- Hire a landscaper if you have a clear idea of what you want and need someone to build it — planting a garden, laying a patio, installing a retaining wall, or tidying up your section.
- Hire a landscape architect if your project is complex, involves significant earthworks or structures, requires resource or building consents, or if you want professional design input before any work begins.
- Hire both for larger residential or commercial projects — a landscape architect designs the space and manages consents, while a landscaping contractor brings the design to life.

When to Call a Professional
For any landscaping project beyond basic garden maintenance, it's worth getting a qualified professional involved early. If your project includes:
- Retaining walls over 1.5 m — likely requires engineering input and building consent
- Significant earthworks or slope modification — may need resource consent
- Plumbing or electrical connections — restricted work requiring licensed tradespeople
- Proximity to boundaries, streams, or protected trees — council rules may apply
A landscape architect can help navigate these complexities, while a skilled landscaper will ensure the physical work is done to a high standard. You can find qualified local landscapers and landscape professionals on tradedirectory.co.nz.
