At Mercer New Zealand, we take our Sustainable Investment Policy into account when managing our investments, believing that sustainable investment approaches are consistent with an objective to create and preserve long-term investment capital, where relevant and aligned with achieving investment objectives.
Our Sustainable Investment Policy is informed by our global philosophy and principles, link here, and our local experience implementing and evolving our sustainable investment approach for over a decade.
We have principles to guide our implementation approach, summarised into four techniques:
Refer to the Sustainable Investment Policy for more information about these principles and implementation techniques.
Mercer New Zealand also publishes a Sustainable Investment Report which provides a summary of sustainable investment activity.
For the Mercer Investment Trusts New Zealand (MITNZ), Mercer Investment Funds and Mercer Wholesale Funds.
Exclusions involve seeking to avoid investing in, or removing exposure as much as practicable to, certain companies with involvement in defined products or business activities.
Exclusions can be used to respond to evolving societal norms and expectations, including New Zealand Government policy positions, especially where Integration and Stewardship are considered to be insufficient or not applicable.
Exclusions are typically implemented as rules-based, pre-defined criteria such as the Exclusions Criteria set out below.
Our application of exclusions is generally determined by the asset class and nature of the holdings, and are subject to the operational limitations and exceptions detailed below.
Exclusions only apply to Directed Investments*. If a Directed Investment meets an Exclusions Criteria, our Investment Managers will generally be expected to divest the Directed Investment in a reasonable period of time, typically within 10 business days and as market conditions allow. We may rely on specialist third party ESG providers and their methodologies for implementation, including determining which securities are required to be excluded based on the relevant Fund’s Exclusion Criteria (see below)
* Please refer to the Sustainable Investment Policy for a definition of Directed Investments
Investment Managers are required to apply the following exclusions to the Directed Investments of the Funds (‘Exclusions Criteria’), unless an operational limitation or exception as noted below, or other factors beyond our reasonable control, mean it is not reasonably feasible or it would be impracticable to apply the exclusions.
Exclusion |
Exclusions Criteria |
Controversial weapons |
Companies that manufacture whole weapons systems, or delivery platforms, or key components that were developed or are significantly modified for use in cluster munitions, anti-personnel landmines, biological or chemical weapons or nuclear weapons. Companies with involvement* in the production or retailing of automatic or semi-automatic civilian firearms or ammunition. |
Tobacco |
Companies with involvement* in the production of tobacco, manufacture of nicotine alternatives or tobacco-based products (regardless of revenue), including subsidiaries and joint ventures. Nicotine alternatives and tobacco-based products include, for example, nicotine vaping products such as ‘vaping’ devices and e-cigarettes.

Defined as:
|
* Involvement is determined by a third party ESG research provider, currently ISS ESG, typically assessed based on revenue derived from defined activities (no revenue thresholds) or in the case of expansion metrics assessed based on capital expenditure. Mercer may change the third party ESG research provider and/or change the scope of its role from time to time.
^ Revenue is gross revenue in the last full financial year or, where not available, net revenue based on available company filings. Mercer may change the third party ESG research provider and/or change the scope of its role from time to time.
# Mercer New Zealand has instructed its investment managers to divest any existing exposure to Russian securities as market conditions allow and to prohibit any new investments in Russian securities. This may mean that some Funds still retain exposures to Directed Investments in Russian securities, as Mercer New Zealand seeks to divest in a manner that promotes the best interests of investors.
Further to the exclusions listed in the Exclusions Criteria section above, additional exclusions also apply for the Responsible and Sustainable Funds (listed in Appendix A of the Sustainable Investment Policy).
Applying Additional Exclusions Criteria may affect investment risks and returns where, for example, there are exclusions to investments in companies that are not typically excluded in other funds. If those excluded companies perform well or poorly in certain time periods, there may be differences in return outcomes compared to a benchmark or comparable fund where those exclusions are not applied.
The Additional Exclusions listed below apply to the Directed Investments of some asset classes – equities, global bonds and global credit – for the Responsible labelled Mercer Investment Funds and the Responsible and Sustainable labelled MITNZ portfolios, as applicable (‘Additional Exclusions’) within certain revenue thresholds, unless exceptions (as noted below) or other factors beyond Mercer New Zealand’s control mean they are not possible to apply.
Other Fixed Income, Overseas Sovereign Bonds and New Zealand Sovereign Bonds asset classes do not have the below Additional Exclusions.

Stewardship approaches
As a shareholder of publicly listed companies, Mercer New Zealand has the right to vote at shareholder meetings and regards voting our shares as an important aspect of Mercer NZ’s sustainable investment approach. For unlisted companies, voting may be undertaken where we have an Advisory Board seat or have certain voting rights in specific funds or individual assets. Stewardship via voting is not applicable for unlisted real assets (i.e. directly held property and infrastructure).
Mercer New Zealand engages the services of a third-party proxy advisor to provide proxy voting research and to facilitate the collation and reporting of proxy voting data which Mercer New Zealand uses to monitor Investment Manager voting. Our ability to directly monitor and report on proxy voting only applies to Directed Investments. Mercer New Zealand’s proxy voting records (to the extent that these are available e.g. for Directed Investments) can be found here and are updated on a six-monthly basis, within three calendar months of the end of the reporting period and show the prior twelve months. Please select Mercer NZ from the regions drop down menu.
Additional information about Stewardship approaches are noted in the - Sustainable Investment Policy.
