Every institutional investor in New Zealand has a document that sets out its investment policy. For managed investment schemes, a Statement of Investment Policy and Objectives is a regulatory requirement under the Financial Markets Conduct Act 2013. For community trusts, charities, iwi, endowments, and family offices, the document goes by different names internationally (investment policy statement is the generic global term), but in New Zealand the convention is the same: the SIPO.
Most institutional boards have one. The question is whether it governs.
A SIPO that governs is a document the board uses. It shapes how the investment committee spends its time. It determines what gets reported and what gets measured. It provides the framework for evaluating whether the advisory arrangement is delivering what the board needs. When a new trustee joins, it is the document that explains not just what the portfolio holds but why, and what the board has decided about the relationship between risk, return, spending, and values.
A SIPO that does not govern is a document the board has. It was written at a particular point in time, often by the adviser, reviewed and approved by the board, and filed. It describes the right things. It may even describe them well. But it does not drive the governance conversation. The board's actual decisions, what gets discussed in committee, what triggers a review, what the reporting measures, operate independently of the document that is supposed to frame them.
The difference between these two versions is not about the quality of the drafting. It is about whether the SIPO functions as the institution's governance operating system: the document that connects every investment governance decision to every other one, and that the board uses as its primary reference when those decisions need to be made or reviewed.
This guide is designed to be useful regardless of where your SIPO sits today. If your board is about to write one for the first time, this provides the framework. If your board has a SIPO that has served well for years, this provides a structured way to test whether it is still doing everything it should. And if your board suspects the document and the governance practice have drifted apart, this provides a way to close that gap.
In This Guide
The SIPO as a governance operating system explains why the SIPO matters beyond compliance, and introduces the concept of the SIPO as the connective tissue between six governance decisions that are often made in isolation.
The six connections is the centrepiece of this guide: a diagnostic framework that maps the six governance decisions your SIPO should connect, what it should say about each, and a question to test whether it does.
Three signs your SIPO has become a filing cabinet document describes the patterns that indicate a SIPO is no longer functioning as a governance tool, even when the document itself is well written.
A framework to take to your next meeting provides practical questions any board can use to begin a SIPO review conversation.
The full guide (available on request) contains a section-by-section reference for SIPO review: what each section should cover, what good looks like, what should concern the board, and the questions to ask. It also covers the SIPO review process, common drafting failures, the relationship between the SIPO and other governance documents, and a board-level SIPO health assessment.
The SIPO as a Governance Operating System
Most boards think of their SIPO as a policy document. It sets out the rules: what the portfolio can invest in, what the risk limits are, what the benchmark allocation looks like, how performance is measured. This is accurate but incomplete. A SIPO that only describes the rules is like a business plan that only describes the budget. It captures one dimension of the governance framework and leaves the rest unconnected.
The more useful way to think about a SIPO is as the governance operating system for the investment function. It is the document that should connect six governance decisions that most boards make at different times, through different processes, and often without explicit reference to each other:
- What is our risk appetite, and how do we express it in terms the board can govern?
- What are our investment objectives, and how do they connect to our institutional purpose?
- What is our strategic asset allocation, and what assumptions does it rest on?
- What is our spending or distribution policy, and how does it interact with expected returns?
- What are our values and responsible investment commitments, and how are they implemented?
- What gets monitored and reported, and does the reporting framework reflect what the board actually needs to govern?
Each of these decisions is important on its own. The governance operating system concept is about the connections between them. A board that sets its risk appetite without reference to its spending policy may be accepting more risk than its distribution obligations can tolerate. A board that adopts a responsible investment framework without embedding it in the SIPO may find the framework is never operationalised. A board that designs its reporting without reference to the SIPO's objectives may be measuring things that do not tell it whether the investment function is on track.
When the SIPO works as an operating system, each of these decisions is documented, the connections between them are explicit, and the board has a single reference point for evaluating whether the investment function is governed coherently. When it does not, each decision sits in its own silo, and the board's governance is only as strong as its collective memory of how the pieces fit together.
The Six Connections
This table names the six governance decisions your SIPO should connect, describes what the SIPO should say about each, and offers a diagnostic question. If these questions are straightforward to answer by reading your SIPO, the document is functioning as a governance operating system. If they require the board to look elsewhere, or to rely on someone's recollection, the SIPO has a gap.
| Governance Decision | What the SIPO Should Say | The Diagnostic Question |
| Risk appetite | How the board defines risk in terms it can govern (drawdown tolerance, probability of capital loss over a stated period, volatility boundaries), not just in technical metrics. The connection between risk appetite and the institution's capacity to absorb a bad outcome. | Can a new trustee read the SIPO and understand how much the portfolio could lose in a severe downturn, and what that would mean for the institution's operations? |
| Investment objectives | The return target expressed in terms that connect to the institution's purpose: the real return required to sustain the spending policy, preserve capital in real terms, or meet a specific liability. Not just "CPI + X%." | Does the SIPO explain why the return target is set where it is, and what would need to change for the board to revisit it? |
| Strategic asset allocation | The benchmark allocation, the rationale for each major asset class, the allowable ranges, and the rebalancing framework. The connection between the SAA and the risk appetite and return objective it is designed to deliver. | Does the SIPO make clear what the SAA is trying to achieve, and under what circumstances the board would review it? |
| Spending / distribution policy | How the spending rate was set, what smoothing mechanism applies, how the spending policy interacts with expected portfolio returns and reserves. For entities without a spending policy, the distribution or drawdown framework. | Can the board confirm, by reading the SIPO, that the spending rate is sustainable given the portfolio's expected return and cost structure? |
| Values and responsible investment | The board's responsible investment commitments (exclusions, ESG integration, impact allocations, stewardship approach), how they are implemented in practice, and how compliance is monitored. | Does the SIPO describe the responsible investment framework in enough detail that a new investment consultant could implement it without further instruction? |
| Monitoring and reporting | What gets measured, how often, against what benchmarks, and what should trigger the board's attention. The reporting framework as a governance output of the SIPO, not a separate document designed by the adviser. | Does the SIPO specify what the board expects to see in its reporting, or does the adviser decide what to report? |
These six connections are not exhaustive. A SIPO covers other matters: liquidity management, currency hedging, manager selection criteria, transition management, conflicts of interest. But these six are the governance connections that matter most, and where the gap between what SIPOs describe and what boards actually use is widest.
Three Signs Your SIPO Has Become a Filing Cabinet Document
A SIPO can be well written and still fail to govern. The document quality is not the issue. The issue is whether the document is embedded in the board's governance practice. Three patterns suggest it is not.
The SIPO and the committee agenda are disconnected. Look at your last four investment committee agendas. How many of the items trace directly back to a section of the SIPO? If the committee spends most of its time on items that are not anchored to the SIPO (manager presentations, market commentary, ad hoc recommendations), the document is not driving the governance conversation. A SIPO that functions as an operating system shapes the agenda. Each standing item should connect to a SIPO section: risk monitoring connects to the risk appetite section, performance reporting connects to the objectives section, responsible investment reporting connects to the values section.
Nobody can remember when it was last substantively reviewed. SIPOs should be reviewed at least every three years, and whenever the institution's circumstances change materially. But many SIPOs are reviewed in a perfunctory way: the adviser presents the current version, suggests minor updates, and the board approves. A substantive review is different. It asks whether the risk appetite still reflects the institution's capacity to absorb loss. It asks whether the return objective is still achievable given current market expectations. It tests whether the spending policy assumptions have held up. It checks whether the responsible investment framework is being implemented as described. If the board cannot remember the last time the SIPO drove a genuine governance conversation, the document has become a filing requirement.
New trustees are not walked through it. One of the most telling indicators. When a new trustee joins the investment committee, what happens? If they receive a copy of the SIPO and are expected to read it themselves, or if they receive the quarterly report but not the SIPO, the document is not functioning as the governance reference it should be. A SIPO that operates as a governance operating system is the first document a new trustee reads, and it is the document that makes every subsequent committee meeting intelligible. If new trustees find the committee meetings difficult to follow, the SIPO may not be doing its job.
A Framework to Take to Your Next Meeting
These questions are designed for any investment committee, regardless of portfolio size, advisory model, or how long the current SIPO has been in place. They are not a scorecard. They are a starting point for a governance conversation about whether the SIPO is doing what it should.
1. When did we last review the SIPO as a governance document, not just as a compliance document?
A compliance review checks whether the SIPO meets regulatory requirements (for managed schemes) or reflects current practice. A governance review asks whether the document is still the right framework for how the board makes investment decisions. The distinction matters. A SIPO can be fully compliant and still fail to govern.
2. Can every committee member explain, from the SIPO alone, why the portfolio is structured the way it is?
This is the operating system test. If the SIPO connects risk appetite to objectives to SAA to spending policy, a committee member who reads it should understand the logic chain. If the logic chain exists only in the adviser's head, or in the collective memory of long-serving committee members, the institution has a governance continuity risk.
3. Does our reporting framework reflect what the SIPO says matters?
Pull out the most recent quarterly report and the SIPO. Compare them. Does the report cover the things the SIPO identifies as important? Does it measure performance against the objectives the SIPO defines? Does it report on the responsible investment commitments the SIPO describes? If the report and the SIPO are telling different stories, one of them needs to change.
If these questions prompt a useful conversation, the full guide provides a structured framework for taking the review further.
Going Deeper
Two of our other research guides connect directly to the governance framework described here.
Spending Policy and Reserves for Perpetual Capital covers one of the six governance connections in depth: the relationship between spending rate, expected return, reserves, and long-term sustainability. If your SIPO's spending policy section is thin, or if the board has never tested whether its spending rate is sustainable, this guide provides the analytical framework.
A Trustee's Guide to Investment Governance is written for the people around the investment committee table. It covers the five questions every trustee should be able to answer after a meeting, and provides the governance context for how the SIPO fits into the board's broader oversight responsibilities.
Both are available as public previews, with full versions available on request.
Starting the Conversation
If the questions in this guide have prompted your board to think about its SIPO differently, the most useful next step is a conversation about your governance framework. Not about whether the document needs redrafting, but about whether the governance operating system is working: whether the connections between risk, return, spending, values, and reporting are explicit, current, and used.
That conversation might lead to a structured SIPO review. It might lead to a different kind of advisory conversation about how the SIPO connects to the broader governance framework. Or it might confirm that your SIPO is already doing what it should, and your governance is in good shape. Any of those outcomes is useful.
If your board would value an independent perspective on its SIPO and governance framework, we welcome the conversation. If a specialist review of your advisory arrangement is more relevant, we can also introduce you to independent search consultants who work with institutional boards.
