Childcare staffing ratios were never validated against child outcomes research

A regulation nobody can defend

Ask any early childhood operator what governs their business and the answer is the ratio. One adult for every five children under two, one for every ten aged two to five, set under the Education (Early Childhood Services) Regulations 2008. Those numbers dictate staffing, rosters, wage costs and ultimately the price parents pay. And according to a Newsroom investigation published this week, officials now concede there is no evidence base behind them. The ratios were never derived from child outcomes research, and have never been validated against any.

The piece opens with a parent whose child had been repeatedly bitten asking a 30-year sector veteran a simple question: is my child safe here? The honest regulatory answer is that nobody can say, because the rule meant to guarantee it was built on nothing.

Why this is a business story, not just a safety one

The child safety framing will dominate the coverage, and fairly so. But early childhood education is not a welfare programme, it is workforce infrastructure. When a centre closes or prices itself out of reach, skilled workers, disproportionately women, cut hours or leave the labour market entirely. Employers already fighting for staff absorb the downstream cost. Any regulation that sets the cost structure of that sector deserves to rest on something firmer than institutional habit.

The supply picture is already deteriorating. Scoop’s February 2026 analysis reported 443 centre closures between March 2022 and July 2025, roughly 100 a year, driven by pay parity obligations and what the industry calls sustained underfunding. Early Childhood Council chief executive Simon Laube put the cumulative gap between government subsidy adjustments and actual inflation at 11.5 percent since 2019. The 20 Hours ECE subsidy is fixed and never rises, while teacher pay increments climb annually, some steps reaching 7 percent. That arithmetic guarantees margin compression, and it will keep shutting centres.

The cost line that hits working families

Average weekly ECE costs climbed from $25.71 in 2007 to $95.45 in 2019, easing to $90.62 in 2023. Government Boost payments introduced in mid-2024 pushed costs down sharply for a year, but between March and December 2025 they rose again by 2.5 percent. At the extreme, some parents now pay more than $15,000 per quarter, and most centres charge $5 to $8 an hour outside the subsidised hours. For a two-income household, that is a direct tax on staying in work.

Deregulating a rulebook nobody validated

Here is where the story sharpens. In 2024 the Education Review Office found half of ECE services fell below the quality threshold on at least one metric. Against that backdrop, the coalition government passed the Education and Training (ECE Reform) Amendment Bill, which reduces teacher qualification requirements and strips back licensing criteria for centre-based services. Critics warned in early 2026 that loosening the rules while half the sector already misses quality benchmarks was the wrong direction.

The deeper problem is symmetrical. If the current ratios have no evidence base, neither does the case for lowering them. The government has deregulated a sector whose baseline rules were never grounded in data. That is not reform. It is compounding the original failure, swapping one set of unvalidated numbers for another and calling it modernisation.

What business should watch

Parents receive guidance that sits above the legal floor anyway. RNZ’s January 2026 advice recommends 1:4 for under-twos and 1:6 for two to three-year-olds, tacitly conceding the regulated minimum is thin. At least three parties now say they will raise ratios, though advocates doubt the political will exists to fund it.

That scepticism is warranted, because better ratios mean more staff, and more staff means higher costs in a sector already bleeding centres. The uncomfortable truth for a pro-business audience is that fixing this cannot be done on the cheap. A regulation that shapes the cost of an entire sector, the childcare bills of working families, and the labour supply of the wider economy has been set and defended for nearly two decades without an empirical leg to stand on. Whoever moves the numbers next should be made to show their working. This time, someone should ask for the evidence before the rule is written.
