The "Refreshed" NZ Maths Curriculum for NZ Schools was published by the Education Ministry in September 2023 by the Labour Government when Chris Hipkins was Prime Minister. Prior to the top job, he was Education Minister. This is what Chippy calls Phase 2 on page 17 of the Curriculum - it's what students should be able to "Do" by end of Year 6:

It is identical to what Hipkins' Refreshed Maths Curriculum calls "Phase 3" on page 23 regards what students should be able to "Do" by End of Year 8. It is identical to what the Curriculum calls "Phase 4" on page 27 regards what students should be able to "Do" by End of Year 10. It is identical to what the Curriculum calls "Phase 5" on page 31 regards what students should be able to "Do" by End of Year 13.
As for what you should "Understand" by the End of Year 6 on page 14, here it is:

It is identical to End of Year 8 as on page 20, End of Year 10 on page 24, and End of Year 13 on page 28. What you should be able to "Do" and "Understand" by end of Year 3 is also strikingly similar to later years.
Seems the Ministry is happy for little development to happen between 5 and 18 years old. The Maths Curriculum is 31 pages long, with so many identical parts that the non-repeating content is tiny. Can the 308 people in the Curriculum Department tell us: (1) Why copy so much when we teach students not to self-plagiarize? (3) Isn't the Ministry engaging in wage-theft, given the Curriculum represents one days work by one person, yet was costed at $100 million? As for the Under Achieving (we can't say Failing anymore) former Minister of Education, Chippy Hipkins, what example did he set our school children? That a lazy, cut-and-pasted scrappy document that was charged out at rip-off prices is a "Pass"?
