Legal Practice Management Software for New Zealand Law Firms

April 2026 · 11 min read

Legal practice management software (PMS) is the central platform New Zealand law firms use to manage matters, track time, handle trust accounting, generate invoices, and store documents. For NZ firms, the choice of PMS has additional weight because it must comply with the New Zealand Law Society (NZLS) trust account regulations, handle 15% GST correctly, and integrate with NZ-specific systems like LINZ and the Companies Office.

New Zealand has approximately 15,000 practising lawyers across roughly 2,000 firms. According to the NZLS 2024 Snapshot of the Profession, the majority of NZ law firms have fewer than 5 practitioners, making cost efficiency and ease of use critical factors in PMS selection. Unlike Australia's more fragmented market, New Zealand has a smaller set of dominant platforms, with Actionstep holding a particularly strong position given its NZ origins.

The NZ PMS Landscape

Five platforms account for the majority of PMS usage across New Zealand law firms. Each has different strengths depending on firm size, practice areas, and budget.

Actionstep

Actionstep was founded in Auckland in 2004 and has the deepest NZ-specific functionality of any PMS on the market. Its trust accounting module is built to meet NZLS requirements, including the Lawyers and Conveyancers Act 2006 trust account provisions and the Trust Account Regulations 2008. It offers native integration with LINZ for e-dealing (electronic property transactions) and the NZ Companies Office.

Actionstep uses a workflow-based approach where each matter type (conveyancing, litigation, family law, etc.) has a configurable workflow template with automated steps. This suits firms that handle repetitive matter types and want consistent processes across practitioners. Pricing is typically NZD $70-120 per user per month depending on the plan and add-ons.

Clio

Clio is a Canadian-founded platform that has expanded aggressively into the AU/NZ market. It offers a clean, modern interface with strong mobile access and a broad integration marketplace (250+ third-party integrations). Clio's NZ trust accounting is functional but less deeply embedded than Actionstep's — some firms report needing to configure custom reports to match NZLS audit requirements.

Clio's strength is its API ecosystem. Third-party tools like LexUnits offer direct API integration with Clio, enabling one-click push of billing entries. This is particularly valuable for firms that want to use AI billing tools alongside their PMS. Pricing starts at approximately NZD $50 per user per month for the Manage plan.

LEAP

LEAP is an Australian-founded platform with a growing NZ presence. It is strongest in conveyancing and property law, with deep integration into Australian state land registries and adapting similar functionality for LINZ in New Zealand. LEAP's pricing model includes the desktop application and cloud access, with costs varying based on firm size and contract terms.

LEAP's NZ market share is smaller than in Australia, partly because its trust accounting module was originally designed for Australian state-level regulations. NZ firms should verify that LEAP's current NZ trust accounting module meets their specific audit requirements before committing.

Smokeball

Smokeball positions itself as a platform for small law firms (1-20 lawyers) and emphasises automation and ease of use. Its automatic time recording feature captures time spent on documents, emails, and phone calls without the lawyer manually starting a timer. Smokeball's NZ market penetration is relatively limited compared to Australia, and firms should confirm NZ-specific trust accounting compliance before adopting.

OneLaw

OneLaw is a NZ-built platform specifically designed for New Zealand law firms. It includes NZLS-compliant trust accounting, LINZ integration, and NZ legal document automation. OneLaw is popular among smaller NZ firms because it was built for the NZ market from the ground up, without the adaptation layer that Australian or international platforms require.

The trade-off is that OneLaw has a smaller developer team and integration ecosystem than Actionstep or Clio. Firms that need extensive third-party integrations may find OneLaw limiting. Pricing is competitive for small firms, typically starting around NZD $60-80 per user per month.

Feature Comparison

Trust Accounting: The Non-Negotiable

Trust account compliance is the single most important factor for NZ firms choosing a PMS. Under the Lawyers and Conveyancers Act 2006, every New Zealand law firm that holds client funds must maintain a trust account that complies with the Trust Account Regulations 2008. The NZLS conducts regular trust account inspections, and non-compliance can result in disciplinary proceedings.

Your PMS must produce trust account ledgers that reconcile with your bank statements, generate the reports required for NZLS inspection, prevent negative trust balances (which are a serious compliance breach), track interest earned on trust funds (where applicable under the Lawyers and Conveyancers Act (Trust Account) Regulations 2008), and maintain a complete audit trail of all trust account transactions.

Actionstep and OneLaw have the strongest NZ trust accounting modules because they were built for the NZ regulatory environment. Clio and LEAP can be configured to meet NZ requirements, but firms should test the trust accounting functionality thoroughly during any trial period.

GST at 15%: What Your PMS Must Handle

New Zealand's GST rate is 15%, compared to Australia's 10%. This sounds like a simple configuration difference, but it affects multiple areas of your PMS: invoice calculations, trust account disbursements (some of which include GST, others do not), BAS-equivalent GST return preparation, and mixed-use apportionment for firms with both taxable and exempt supplies.

Your PMS should allow you to record all time entries and rates GST-exclusive, then calculate 15% GST at the invoice level. This is consistent with Inland Revenue Department requirements and ensures clean GST return preparation.

Third-party billing tools should also submit rates GST-exclusive. LexUnits, for example, generates all billing entries with GST-exclusive rates — the firm's PMS handles GST calculation at the invoicing stage, regardless of whether the firm is in Australia (10%) or New Zealand (15%).

AI Billing Tools and NZ Practice Management

The gap between what your PMS can do (store and invoice time entries) and what it cannot do (create entries from your daily work) is the same in New Zealand as in Australia. AI billing accelerators fill this gap by converting meeting recordings, emails, and documents into structured time entries.

For NZ firms, the key requirements for an AI billing tool are support for NZ legal terminology and conventions (which differ from Australian usage in some areas), 15% GST awareness (entries must be GST-exclusive), NZLII integration for case law references (rather than AustLII), and export compatibility with your specific PMS.

Currently, the integration options for NZ firms are: direct API push to Clio (available now through tools like LexUnits), Actionstep-formatted XLSX export (with direct API integration in development), LEAP-formatted XLSX export, and Smokeball-formatted XLSX export. OneLaw users currently need to use the generic export format and map fields manually.

Migration Considerations

Switching PMS platforms is a significant undertaking. According to a Thomson Reuters survey of AU/NZ firms that migrated PMS platforms, the average migration project takes 3-6 months from decision to full deployment. The most common challenges are data migration (particularly trust account history and active matter details), staff training and adoption (the number one reason PMS migrations fail is lawyer resistance to the new system), workflow reconfiguration (matter templates, document automation, and email integration), and downtime management (most firms cannot afford to shut down for a full migration, requiring a parallel-running period).

Before migrating, calculate the total cost of switching, including the new platform's licensing fees, data migration costs (some vendors charge separately), training time (typically 4-8 hours per user for basic proficiency), and productivity loss during the transition period (typically 2-4 weeks of reduced efficiency).

What is the most popular practice management software in New Zealand?

Actionstep holds the largest market share among NZ law firms. Founded in Auckland in 2004, it has native NZ trust accounting, LINZ e-dealing integration, and NZ Companies Office connectivity. Clio has been growing its NZ user base with a strong API ecosystem and competitive pricing. OneLaw is the other NZ-native option, popular with smaller firms that want a platform built specifically for the NZ legal market.

Do New Zealand law firms use 6-minute billing units?

Yes. The 6-minute unit system (dividing each hour into ten billable units) is the standard billing convention in New Zealand, identical to Australian practice. All major PMS platforms used in NZ support 6-minute unit recording. Lawyers record time in these units, and invoices are calculated based on the number of units multiplied by the hourly rate.

How does GST work for legal billing in New Zealand?

New Zealand applies 15% GST on legal services under the Goods and Services Tax Act 1985. Your PMS should record all hourly rates and time entries GST-exclusive. GST is then calculated and applied at the invoice level. This ensures clean separation between the service fee and tax component, simplifies GST return preparation for the IRD, and is consistent with how third-party billing tools like LexUnits handle NZ entries.
