Electromagnetic Compatibility (EMC) — RCM / EESS Evidence China EMC evidence often cites GB/T 17626, GB 17799, GB/T 9254, or CCC EMC reports. These are frequently technically aligned with IEC or CISPR source standards, but the reports may use China-only standard titles, China model configurations, and China supply assumptions.GB/T 17626 series — EMC testing and measurement techniques
GB 17799 series — Generic EMC standards
GB/T 9254 series — Information technology / multimedia emissions standards
CCC EMC evidence where applicable		 New Zealand BESS electrical and electronic components should be supported by EMC evidence compatible with the RCM claim and the product's intended environment. Applicable evidence may include AS/NZS CISPR 11 or AS/NZS CISPR 32 emissions testing, IEC / AS/NZS 61000-series immunity evidence where required by product classification or contract, and technical documentation held by the New Zealand importer or supplier. EMC evidence is part of the same market file as electrical safety evidence under the RCM / EESS approach.RCM — compliance mark for applicable electrical and electronic equipment
AS/NZS CISPR 11 — EMC emissions for industrial, scientific, and medical equipment
AS/NZS CISPR 32 — EMC emissions for multimedia equipment where applicable
IEC / AS/NZS 61000 series — EMC immunity and test methods where applicable
Electricity (Safety) Regulations 2010 — New Zealand electrical safety framework		 The report package should show that EMC testing covers the New Zealand-supplied configuration, including PCS/inverter, BMS, communication equipment, enclosure, cabling assumptions, and 230/400 V, 50 Hz operation where relevant. China-only GB reports may need mapping to AS/NZS or IEC/CISPR titles and may not support an RCM claim without a New Zealand supplier technical file.[INFORMATIONAL] Chinese EMC reports can be useful technical evidence, but a New Zealand BESS supplier should map them to AS/NZS or IEC/CISPR requirements and keep a technical file that supports the RCM / EESS compliance claim for the actual New Zealand configuration.

Grid Connection & Inverter Approval — AS/NZS 4777.2 and Local Distributor China grid files commonly cite GB/T 36558-2023 for electrochemical energy storage systems and NB/T 42090-2016 or related NB/T standards for PCS and station equipment. China grid connection is designed around Chinese 220/380 V, 50 Hz low-voltage assumptions or project-specific medium-voltage connection studies. Those reports do not establish New Zealand AS/NZS 4777.2 compliance or local distributor approval.GB/T 36558-2023 — China electrochemical energy storage grid requirements
NB/T 42090-2016 — China energy-industry standard for storage station / converter equipment
China grid-company project connection approval		 Grid-connected BESS and their PCS/inverters must be configured for New Zealand's 230/400 V, 50 Hz supply and comply with AS/NZS 4777.2 where applicable. Connection approval is not granted by a national product list alone: the Electricity Authority sets the regulatory framework, while the local electricity distributor or lines company assesses distributed generation connection applications, protection settings, export limits, metering, and network constraints before energisation.AS/NZS 4777.2 — Grid connection of energy systems via inverters, inverter requirements
Electricity Industry Participation Code — distributed generation connection framework
Electricity Authority — New Zealand electricity-market regulator
Local electricity distributor / lines company connection approval		 The inverter must use New Zealand region settings and protection values, not Australian-only or China-only defaults. The local distributor may impose export limits, dynamic control, anti-islanding, metering, or commissioning evidence beyond the manufacturer's generic AS/NZS report. Chinese GB/T grid tests do not replace AS/NZS 4777.2 evidence or the local connection agreement.[INFORMATIONAL] A China-made grid-connected BESS should not be commissioned in New Zealand until AS/NZS 4777.2 evidence, New Zealand inverter region settings, and local distributor connection approval are resolved. China GB/T grid-connection reports are not New Zealand approvals. Electricity Authority Te Mana Hiko2026-06-14 · unverified
Fire Safety & Installation Code — AS/NZS 5139:2019 China design packages may use GB 51048 for electrochemical energy storage station design, GB/T 36558-2023 for electrochemical energy storage systems, and project fire design review under Chinese building-fire rules. These China documents do not map directly to New Zealand's AS/NZS 5139 location and clearance method, AS/NZS 3000 wiring practice, FENZ interface, or local council building-consent process.GB 51048 — Design code for electrochemical energy storage station
GB/T 36558-2023 — General technical requirements for electrochemical energy storage systems in power systems
China building and fire design review rules for energy-storage projects		 AS/NZS 5139:2019 is the New Zealand installation safety standard for battery systems used with power conversion equipment, alongside AS/NZS 3000 wiring rules and the Electricity (Safety) Regulations 2010. It addresses location, separation, ventilation, signage, protection, documentation, and emergency information. Fire and Emergency New Zealand may be involved through fire-engineering, emergency-response, or building-design review, and building consent under the Building Act may be required depending on the site, size, enclosure, occupancy, and council interpretation.AS/NZS 5139:2019 — Electrical installations — Safety of battery systems
AS/NZS 3000 — Electrical installations wiring rules
Electricity (Safety) Regulations 2010 — New Zealand electrical safety regime
Building Act 2004 — building consent may apply depending on installation
Fire and Emergency New Zealand — fire safety and emergency-response stakeholder		 AS/NZS 5139 clearances, restricted locations, ventilation assumptions, warning labels, emergency procedures, and installer documentation must be prepared for the New Zealand site. Factory drawings based on Chinese station design codes are not enough. The installer must also resolve AS/NZS 3000 wiring details and any council, building-consent, or FENZ fire-safety review before commissioning.[INFORMATIONAL] A New Zealand BESS installation should be checked against AS/NZS 5139:2019, AS/NZS 3000, site-specific fire-safety assumptions, and any building-consent or FENZ review route. Chinese GB or project fire-design approvals are not substitutes for the New Zealand installation file. Fire and Emergency New Zealand2026-06-14 · unverified
RCM Mark & EESS Evidence — New Zealand Market Access China market access usually relies on CCC, CQC voluntary certification, CNAS laboratory reports, and domestic GB or NB/T standards. These may support engineering review, but they do not create an RCM claim, a New Zealand supplier declaration, or EESS evidence accepted under New Zealand's electrical safety regime.CCC — China Compulsory Certification
CQC voluntary certification
CNAS-accredited laboratory reports
GB/T 36558-2023 / GB/T 34120-2023 / NB/T 42090-2016 — China BESS technical standards		 New Zealand uses the RCM as the compliance mark for in-scope electrical and electronic equipment, supported by supplier declarations, technical files, and EESS / ERAC arrangements where applicable. The legal basis is the Electricity (Safety) Regulations 2010, administered by WorkSafe / Energy Safety. For BESS, importers and suppliers should hold evidence for the battery system, PCS/inverter, BMS, switchgear, EMC, and installation interface before supply. This is distinct from Australia: New Zealand uses many of the same AS/NZS standards but the responsible regulators, market documents, and local approvals are New Zealand-specific.Electricity (Safety) Regulations 2010 — product and installation safety requirements
WorkSafe New Zealand / Energy Safety — electrical safety regulator
RCM — regulatory compliance mark for applicable electrical and electronic equipment
EESS / ERAC — supplier and equipment registration arrangements where applicable		 The supplier must be able to justify the RCM / EESS compliance claim with New Zealand-relevant evidence. CCC and China GB reports are not mutually recognized as New Zealand approval. Unlike Australia-specific CEC product listing pathways, New Zealand market access focuses on WorkSafe / Energy Safety electrical safety duties, RCM / EESS evidence, local installation compliance, and distributor connection approval.[INFORMATIONAL] China CCC, GB/T, or NB/T evidence does not by itself authorize New Zealand supply. A New Zealand BESS file should support the RCM / EESS claim under the Electricity (Safety) Regulations 2010 and identify the importer or supplier responsible for compliance.

Cell & System Safety Certification — IEC 62619 / IEC 62133 / IEC 62040 China BESS technical files often cite GB/T 36558-2023 for electrochemical energy storage systems in power systems, GB/T 34120-2023 for battery management systems, and NB/T 42090-2016 for electrochemical energy storage station equipment or PCS-related requirements. These documents are useful for understanding China-market design intent, but they are not New Zealand approvals and do not replace IEC-titled safety reports, RCM / EESS evidence, or AS/NZS installation evidence.GB/T 36558-2023 — 电力系统电化学储能系统通用技术要求
GB/T 34120-2023 — 电化学储能系统储能变流器 / 电池管理系统相关中国技术要求
NB/T 42090-2016 — Electrochemical energy storage station equipment / converter-related China energy-industry standard		 Battery cells, battery systems, power conversion equipment, and related electrical assemblies supplied in New Zealand must be supported by product-safety evidence appropriate to their function and risk under the Electricity (Safety) Regulations 2010 and the RCM / EESS framework used by New Zealand electrical safety regulators. For lithium BESS, the relevant technical evidence normally includes IEC 62619 for industrial lithium cells and batteries, IEC 62133 for portable sealed cells where relevant, IEC 62040 for UPS-type assemblies, and installation evidence under AS/NZS 5139:2019. The New Zealand low-voltage supply is 230/400 V, 50 Hz, so ratings and protection settings must be documented for that supply system.Electricity (Safety) Regulations 2010 — New Zealand electrical safety regime
RCM / EESS — regulatory compliance evidence for in-scope electrical equipment
IEC 62619 — Safety requirements for secondary lithium cells and batteries for use in industrial applications
IEC 62133 — Safety requirements for portable sealed secondary cells and batteries
IEC 62040 series — Uninterruptible power systems
AS/NZS 5139:2019 — Electrical installations — Safety of battery systems		 The key gap is not only technical testing, but regulatory acceptability. IEC 62619, IEC 62133, IEC 62040, RCM / EESS evidence, and AS/NZS 5139 installation documentation must be traceable to the product configuration supplied to New Zealand. China-only GB/T or NB/T reports are not accepted as substitutes. Nameplate ratings, BMS limits, protection functions, and PCS settings must be suitable for New Zealand's 230/400 V, 50 Hz supply rather than China's common 220/380 V configuration.[INFORMATIONAL] A China-made BESS supported only by GB/T 36558-2023, GB/T 34120-2023, or NB/T 42090-2016 evidence should not be treated as New Zealand-ready. The product safety file should include IEC 62619 / IEC 62133 / IEC 62040 evidence as applicable, RCM / EESS documentation, and configuration proof for New Zealand 230/400 V, 50 Hz operation.

Lithium Battery Dangerous-Goods Transport — UN 38.3 China exporters also use UN 38.3 for lithium battery export, with supporting dangerous-goods documentation for sea and air shipments. This is the closest alignment area between China and New Zealand. However, Chinese domestic road-transport rules and Chinese-language shipping papers are not enough for New Zealand import, local storage, or onward carriage.UN 38.3 — same international test requirement for lithium battery export
GB 12268 — China list of dangerous goods
JT/T 617 — China road transport of dangerous goods		 Lithium batteries shipped to New Zealand must satisfy UN 38.3 test requirements in the UN Manual of Tests and Criteria and be classified, packed, marked, labelled, and documented under the applicable sea, air, and domestic dangerous-goods transport rules. BESS shipments commonly involve UN 3480, UN 3481, or large battery / cargo transport unit classifications depending on the shipping configuration. The UN 38.3 test summary should match the actual cell and pack configuration supplied.UN 38.3 — UN Manual of Tests and Criteria, Part III, Section 38.3
IMDG Code — sea transport of dangerous goods
IATA Dangerous Goods Regulations — air transport of dangerous goods
UN 3480 / UN 3481 / UN 3536 — common lithium battery classifications depending on configuration		 UN 38.3 evidence is transferable only if it matches the shipped configuration and is accompanied by correct English-language dangerous-goods documentation. The importer and carrier must confirm New Zealand handling, storage, port, road, and emergency-response requirements for the specific UN number and packaging method. China domestic dangerous-goods documents do not replace New Zealand transport compliance checks.[INFORMATIONAL] UN 38.3 is necessary for lithium BESS transport to New Zealand, but it is not a full market-access approval. The shipped configuration, UN number, packaging, labels, safety data, and New Zealand carrier documentation still need project-specific verification.
