The National Party says households would get between $20 and $250 a fortnight under its tax relief plan.
Party leader Christopher Luxon won't reveal how it will pay for the package until the full details are released later this morning.
Luxon told Morning Report it's about helping those on low and middle incomes.
"No matter how hard they work, they just can't get ahead, and they've been hammered by this government with inflation and interest rates and high taxes eating away their income."
"So, we've been really purposeful and very intentional to say, these are the people that we're helping with this tax relief and this tax plan.
It means that we're actually capping what people above $78,100 get. They'll get the same dollar amount whether you're a millionaire or you earn $80,000 a year, it's the same."
Luxon said the tax cuts will be funded by four new ways to raise revenue and spending cuts.
