Independent Client-Side Construction Project Management & Advisory – New Zealand & Pacific

Buyer Created Tax Invoices can streamline payment administration on construction contracts — but used incorrectly, they create exactly the disputes they were meant to avoid.

The most common mistake principals make is treating a BCTI as a substitute for a payment schedule. It isn't.

This guide explains what BCTIs are, where the risks lie, and what good implementation actually looks like under New Zealand's Construction Contracts Act 2002.

Most fixed-price construction contracts under NZS 3910 carry no active fluctuations clause — meaning fuel cost escalation sits with the contractor by default.

But when both parties agree that a genuine, material cost increase warrants consideration, the question becomes: on what basis, and how?

BPM's 7-Point Test provides a consistent, defensible method for assessing fuel cost adjustment claims — one that replaces ad hoc negotiation with a clear, auditable process that protects both parties.

Fuel price volatility doesn't just affect contractors — it affects programme, cost, and project outcomes at every level of the delivery chain. This guide is written for principals, developers, and asset owners procuring and managing construction work in New Zealand.

It covers how to structure contracts that reflect fuel risk appropriately, when and how the NZS 3910 (for example) fluctuations clause applies, what the National Fuel Plan means for your live projects, how to assess and respond to contractor claims on contractual grounds, and what signs of contractor financial stress to watch for before they become a crisis. Practical, legally grounded, and written for the current New Zealand market.

New Zealand's water infrastructure is under pressure from every direction - ageing assets, a tightening regulatory environment, decades of deferred investment, and a climate that is making existing systems less reliable.

Whether you manage a wastewater treatment plant, a school bore, a retirement village supply, or a new subdivision, the rules have changed and the scrutiny has increased. This free guide explains who regulates what, what the law now requires of you, the warning signs that your infrastructure is at risk, and why acting early costs less than acting late.
