National MPs talked so long their own minister couldn't answer questions

National is being accused of undermining Parliament's ability to hold ministers to account, after its own MPs used up the speaking time allocated to Social Development Minister Louise Upston, leaving her unable to answer Opposition questions.

The clash happened in Parliament on Tuesday during what is called an Estimates debate. This is a process where MPs get to question ministers about how public money in the Budget will be spent. The debate runs for 11 hours over several days. Each party gets a set amount of speaking time, and the party's whips — the MPs who organise their party's business in Parliament — decide who gets to speak and for how long.

Near the end of Tuesday's session, Upston, there to answer questions as Social Development Minister, said she could not keep going because her time had run out.

Committee chair Greg O'Connor had earlier warned MPs to be mindful of the time. He told the committee that Upston's own colleagues had "misappropriated her time" — meaning National MPs had used up speaking slots that could have been saved for the minister to respond to questions. RNZ

Greens MP Ricardo Menéndez March then offered Upston 15 seconds of his party's speaking time so she could give yes-or-no answers to his questions. O'Connor allowed it. Upston answered one more question, then went silent for the rest of the session.

Menéndez March said ministers are within their rights to stop answering when their time is up. But he argued that using speaking time for long speeches instead of engaging with direct questions was a deliberate tactic to run down the clock and avoid scrutiny. He said he did not get proper answers on whether any beneficiaries lost payments under a recent policy change, or on cuts to the accommodation supplement for low-income homeowners.

The broader issue here is a long-standing flaw in how the Estimates debate works. Think of it like a courtroom where the defence gets to decide how much time the witness has to answer questions, and can use most of that time giving speeches instead. The rules give parties control over how their time is divided, but nothing requires a governing party to set aside time for the minister to actually answer questions. In practice, government whips can give speaking slots to their own MPs for speeches, knowing the minister will still be called to speak but with too little time left to face real questioning.

That is not a new complaint, but it rarely surfaces so openly. O'Connor's decision to use his position as chair to state on the record that the minister's own side had used up her time put the issue in the public record, rather than leaving it as a complaint raised by the Opposition after the fact.

Upston told the House that National had suggested trialling a change to the Estimates format to make sure ministers would not run out of time. She agreed the current format does not work as it should, and said the government had tried to fix the system but not all parties agreed on the proposed changes. RNZ

That admission is notable. Ministers usually defend parliamentary procedure as working fine, or brush off complaints as Opposition posturing. Upston's concession that the format is not working as intended, along with the fact that National actively proposed a trial change, puts the government on record as acknowledging the problem, even as the Opposition argues the government's own conduct on Tuesday showed the problem in action.

The disagreement among parties over what a fix should look like leaves the Estimates format unresolved. Without cross-party agreement on rule changes or procedural trials, the current system stays in place: government whips control time allocation, and there is no rule requiring them to reserve ministerial time for questioning. The status quo will persist until either parties reach a consensus or a future government with enough numbers forces a change through the Standing Orders Committee, which sets Parliament's rules.

For those who work in and around Parliament, the episode is a reminder that the Estimates debate works as a scrutiny tool only if parties choose to use their time that way, and that the parties best placed to exploit the gap are the ones whose ministers are under pressure.
