Akash Gill and Ross Kinnerley were batting and looking to recover the innings when the rain fell.
The only other match which got more game time was at Queen Elizabeth Park in Masterton, where Red Star managed to bat a full first innings, being bowled out by Levin Old Boys for 170 in the 43rd over.
Top scorer was opener Dion Knight with 40 from 105 balls as he lost partners with regularity, while Jeremy Osborne led a bit of a fightback by the lower order with 31.
Levin's Dion Sanson (3-19) got the prized wicket of Knight, while Alex O'Malley (3-30) cleaned up the middle order, but their team did not get the chance to chase the low target.
Coastal Challenge will continue this coming Saturday as Property Brokers United hosts Paraparaumu in a rematch of the grand final for the past two seasons, while Tech will be the first local team to venture to the Wairarapa Bush region as they face Red Star in Masterton.
Marist and Wanganui Collegiate 1st XI also head out of town to take on Levin Old Boys and Kapiti Old Boys respectively.
On Sunday, Hartley will select his first Wanganui XI to face Wellington A in a warmup game to the representative season.
