The S&P/NZX 50 index has breached the 14,000 mark for the first time, closing at a new record high of 13,976.67 on Tuesday.
The milestone caps a three-day rally that has lifted the benchmark by more than 2%, with the index touching an intraday high of 14,000.25 before settling.
This follows a previous record close of 13,850.69, which saw the index rise 78.40 points or 0.57% in the prior session.

Lower energy costs have provided a tailwind for the New Zealand market, reducing input costs for businesses and improving consumer spending power.
The momentum has been consistent, with the index breaking through previous resistance levels to establish a new baseline for valuations.
Market participants are now watching for signs of whether this momentum can be sustained in the coming weeks.
The recent performance has outpaced broader regional peers, highlighting the resilience of the New Zealand equity market amid global uncertainty.
