To move an existing New Zealand contractor into employment, agree the package and service treatment, confirm the prospective employer is ready, and coordinate the supplier exit with the employee start. Check historical status and work permission first. Then assign the later payday filing, IRD payments and ACC invoice to named owners.

What changes when a contractor becomes an employee in New Zealand?
Use one transition record linking the existing supplier agreement, accepted employee terms and payroll dates.
Establish status, work rights and the employment route
Check the history before choosing an employment start
New Zealand's status guidance incorporates a gateway test effective from 21 February 2026. It requires all criteria covering the written agreement, other clients, timing or subcontracting, declining additional work, and independent advice. Failing the gateway sends the relationship to the common-law assessment; it does not automatically make the person an employee.
The change is not retrospective. Examine earlier work under the earlier common-law framework. Where the facts indicate existing employment, assess the supported start and outstanding rights before treating conversion as a fresh start.
Choose the actual employing organisation. A New Zealand company can operate the domestic payroll illustrated below. For a foreign company, IRD's rules distinguish sufficient local presence, benefits and superannuation obligations from cases involving employee tax accounting. Foreign-employer registration does not settle the separate corporate-registration question. Where an overseas company starts carrying on business here, Companies Office guidance specifies registration within 10 working days.
An EOR is another arrangement to assess. Name the employing company and allocate payroll responsibilities. For AEWV workers placed with an ordinary commercial host, immigration instructions require the employer to check the host's NZBN and compliance, check employment and safety conditions before placement, and monitor them afterwards. An EOR contract does not resolve visa eligibility or corporate-tax presence. For the broader arrangement, see our New Zealand EOR guide.
Check the worker's actual visa conditions. Employer, occupation or location restrictions can require permission to change before the proposed employee work begins. Previous permission to perform services is insufficient evidence for a different arrangement.
Agree the offer, start date and treatment of existing rights
Give the worker a draft employment agreement, time to obtain advice, and an opportunity to negotiate before starting. Include the required clauses, parties, duties, workplace, hours, pay and payment method. Check any applicable collective agreement.
The following proposal assumes permanent weekday employment. The enacted leave replacement starts on 6 August 2028; current Holidays Act rules must continue until then.
Do not use a new trial as a standard conversion clause. Trial restrictions include prior work and AEWV limitations; establish eligibility for the actual history before considering one. Probation also preserves ordinary employee rights.
Confirm the employer handoff before supplier exit
Nominate a client lead to supply the contractor agreement, supplier identity, notice/consent terms, last-service and final-invoice details, expenses and existing IP records. The worker supplies accepted terms, work-permission evidence, IR330, bank details and KiwiSaver instructions.
Before making supplier termination irreversible, obtain the prospective legal employer's confirmation of accepted terms, supported service and opening leave, permission for the job, coverage and payroll readiness, and start date. With an EOR, record who confirms each item and owns filings/payments for this arrangement.
A provider application is not readiness evidence. Later statutory filings and payments can fall after employment starts; keep them scheduled with owners.
Separate existing IP from future employee work
New Zealand's copyright guidance distinguishes employee-created work from commissioned work. Software created in employment generally belongs first to the employer; paid commissioned computer programs can already belong to the commissioner, subject to contrary agreement. That commissioning rule does not cover every type of written deliverable.
Check commissions, assignments, third-party licences and background tools. Obtain missing rights from the proper owner, then define future employee IP and confidentiality. The new clause does not establish title to all earlier work or every invention.
Compare the old invoice with the employee package
This hypothetical negotiation compares an NZD8,000 monthly fee before GST and reimbursable expenses with NZD90,000 annual gross salary plus employer KiwiSaver. There is no prescribed ratio or guarantee of equal take-home pay.
The proposal reduces annual gross cash from NZD96,000 in fee revenue to NZD90,000 in salary. Salary plus the annualised gross employer KiwiSaver contribution is NZD93,150, before employer ACC and any other costs. Paid leave and reimbursed expenses still need their own agreement; this subtotal does not value them or establish equal net pay. The default rate is 3.5%, subject to eligibility and notices. ESCT ordinarily reduces the gross employer contribution.
For the November starter below, five monthly salaries plus gross employer contributions through 31 March total NZD38,812.50. Under the new-starter ESCT rules, the assumed estimate gives a 17.5% band. Applying IRD's whole-dollar method gives NZD45.85 ESCT and NZD216.65 net employer contribution. Bonuses or different earnings can change that estimate. Payroll must calculate PAYE from the real tax code; these figures are not a net-pay quote.
Complete the country conversion steps
- Client lead: assemble the handoff. Establish the supplier, legal employer and historical-status position. Keep the contract, work-rights evidence and outstanding decisions together.
- Employer and worker: accept the terms. Complete the offer and readiness confirmations above. Record any conditions that prevent confirming the start.
- Client and actual supplier: agree closure. Apply the services contract, using notice or written consent. Sign only for a date the employment arrangement can support.
- Employer/payroll: enable employment. Register with IRD as soon as employing begins; the calendar uses an advance target. Establish time/leave records, induction and ACC classification. Retain setup confirmation.
- Worker/payroll: validate inputs. Use employee IR330, not the old contractor declaration. An existing KiwiSaver member supplies KS2 and is not auto-enrolled again. Check any student-loan, child-support or other notices.
- Payroll/finance: execute the calendar. Submit separate starter details, pay wages, file and remit on the applicable dates below. Confirm the filer and payer for this arrangement.
- Transition lead: reconcile the evidence. Close the supplier and first-pay records using the next section. Keep the later ACC invoice assigned until settled.
Worked Auckland cutover calendar
Illustrative assumptions: a newly formed NZ company already has an IRD number and is employing its first worker in Auckland. It files electronically and falls below NZD500,000 annual PAYE plus ESCT, with no connected-business threshold effect. The worker is 30, a resident with unrestricted work rights, already in KiwiSaver, with no suspension, temporary rate reduction, student loan, child-support notice, bonus or fringe benefits.
Genuine contractor services end Friday 30 October 2026. Permanent employment starts Monday 2 November. The parties agree NZD7,500 gross for November, paid monthly on Monday 30 November, rather than applying an assumed statutory proration formula. Salary continues unchanged through March for ESCT.
The monthly remittance rule and weekend adjustment determine the December payment rows. Different employer categories or filing methods need an adapted schedule.
There is no additional Auckland payroll-tax registration, return or remittance for this ordinary wage payroll. Official tax-system guidance distinguishes the absence of local payroll and social-security taxes from property rates. KiwiSaver and ACC obligations still apply.
ACC employer invoicing is separate from PAYE. New-business invoicing follows the first tax return, usually in the second business year. Cover is not postponed until invoicing. Keep that charge open after the December payroll reconciliation and substitute the real invoice deadline when issued.
Close the contractor engagement and verify first payroll
Closeout needs evidence, not another copy of the plan.
For the supplier file, retain:
- The proper party's exit agreement and reconciled final invoice, GST, expenses and settlement evidence.
- Accepted deliverables, IP assignments/licences, equipment and access handover, and any continuing insurance or confidentiality terms.
- Matching service and employment periods, with no unintended missing work or duplicate charge.
For the first employee cycle, retain:
- Payroll register and bank credit matching gross salary, employee deductions and net pay, with employer contribution and ESCT shown separately.
- Confirmed opening leave and benefit records, employer setup, separate starter confirmation, and accepted employment information.
- Settled IRD payment and correct period allocation, plus an open ACC follow-up until its invoice is paid.
- Delivery of the promised breakdown. Payslips are not universally required unless promised by agreement; mandatory wage, time and leave records and access rights remain.
Two conversion situations to plan for
A planned conversion (hypothetical). An independent Auckland developer wants holiday during the first year of employment. The parties use the calendar above, but agree access to annual holidays in advance rather than assuming a day-one statutory balance. The prospective employer records that enhancement before supplier closure; it keeps the supported employment anniversary separately.
Earlier employment (hypothetical). Suppose the worker has followed fixed shifts under close supervision since 2025 and the gateway conditions are not all met. Those facts require a historical status assessment, including the pre-February period. If earlier employment is established, the proposed November date cannot reset statutory service or erase unpaid entitlements. Resolve opening balances and corrections from the evidence; do not obtain a routine waiver as the conversion step.
Questions about converting contractors in New Zealand
Must the salary equal the old invoice?
No prescribed ratio applies. Use the bridge above to agree cash, paid leave, expenses and employer contributions. A lower gross salary does not establish equal take-home pay.
Can we end the supplier agreement as soon as an EOR accepts our application?
An application is not confirmation of accepted employment terms, permission, payroll readiness or a start. Use the employer handoff above before making the supplier exit irreversible.
Does an existing KiwiSaver member get a new opt-out?
Do not treat conversion as new automatic enrolment. Obtain current membership and deduction instructions and notify IRD of the employment.
Must December tax payments be completed before November employment starts?
No. Establish start readiness first, then meet the scheduled declarations and remittances. An accepted return is separate from settled money; the later ACC invoice also needs an owner.
