The column that matters on a UK data team's transfer register is the one marked EU, and this pledge does not tell the person maintaining it what to write there. Adequacy is why that column currently carries no extra work: it lets personal data move between the UK and the bloc without additional legal machinery, and Brussels extended it until 2031 in December [7].
Put the two regimes side by side and the difference concentrates in enforcement. The Information Commissioner can issue multi-million-pound fines, while New Zealand's Privacy Act 2020 caps penalties at NZ$50,000, a figure The Register set against it [4]. The rights are narrower too, with no equivalent of the right to be forgotten [6]. On the mechanics of handling and transferring data, the two regimes sit closer than the rhetoric suggests [5], which is awkward for a plan sold on the claim that GDPR has strangled small businesses and tech firms alike in a web of unnecessary regulation [20].
That gap tells you who the pitch is for. Fine-scale exposure is real: Dutch regulators used the EU regulation this month to fine Uber 825m euros over automated driver suspensions [12], and at home NHS England admitted in July that its paperwork hid a disclosure about who could see identifiable patient data [15]. If your worst case is a penalty with commas in it, a NZ$50,000 ceiling is worth money. If your privacy cost is the recurring hour someone spends on subject access requests and record-keeping, the mechanics stay roughly where they were [5], so the relief is thinner than the announcement.
The adequacy claim is where a data team should spend its scepticism. The Commission grants adequacy only where protection is essentially equivalent, and any major divergence puts the decision at risk [8]. Reform's press release asserts that the New Zealand model clears that bar, and does not say how [9]. Divergence is not automatically fatal, and last year's Data (Use and Access) Act showed as much, easing data sharing between critical sectors and softening rules on automated decision-making while adequacy held [11]. Removing the fine ceiling and trimming individual rights is a bigger move than that one was.
The bill, if the bet loses, is specific. Firms that lose free flows fall back on standard contractual clauses, which is paperwork, and every small business in Reform's package would pay for it [10]. Note the constituency being courted: the same package raises the VAT registration threshold from 90,000 pounds to 150,000 pounds [17], a rise of 60,000 pounds or about 67% [18]. Firms at that size are precisely the ones for whom a stack of clauses is a genuine cost and an ICO mega-fine is not a live scenario.
One more data point on how the current law behaves in practice: the Good Law Project sued Reform UK in March 2025, saying the party refused to tell people what data it held about them and did not answer requests to delete it, and a High Court judge ruled in June that the case should proceed to trial [13]. Reform UK did not respond to The Register's request for information about its pledges [14].
The split worth drawing is two by two. One axis is whether personal data crosses between your systems and the EU. The other is whether your largest privacy cost is a plausible fine or a recurring process. Domestic-only and fine-exposed is the single box where a New Zealand-style regime is straightforwardly cheaper for you. Cross-border and process-heavy is the box where you keep the process and add the clauses on top.
