Michael Venus is the lone New Zealand representative left in the ASB Classic after going through to the men's doubles semi-finals alongside South African partner Raven Klassen on Thursday.
Venus and Klassen beat Joao Sousa of Portugal and Guido Pella from Argentina 7-5, 6-3 to reach the final four where they will face American brothers Bob and Mike Bryan for a spot in Saturday's final.
Last year, Venus and Klassen were eliminated in the semi-finals in Auckland, and the pair went on to have a successful 2018 campaign which saw them reach five finals, including at Wimbledon where they lost to Mike Bryan and Jack Sock in five sets.
Venus is a previous doubles champion in Auckland (2016 with Mate Pavic) and also reached the last four in 2012 alongside compatriot Daniel King-Turner.
The Bryan brothers beat Kiwi Artem Sitak and American partner Austin Krajicek 6-7, 6-2, 2-10 in the quarter-finals.
Fellow Kiwi Marcus Daniell and Dutch partner Wesley Koolhof was also eliminated in the quarter-finals, losing 7-6, 7-6 to Queenstown-born Japanese player Ben McLachlan and Germany's Jan-Lennard Struff.
McLachlan and Struff will face Austria's Oliver Marach and Croatia's Mate Pavic in the other semi-final.
