Ben Fraser was the leader of the pack for Launceston as the opening bowler proved a constant thorn in Ulverstone's side to secure a five-wicket haul.
Fraser trapped Black Caps opener Brayden DeVries in front before he doubled the dose to get Jason Snare in the same fashion. When Fraser had James Kelly caught off a length, the Black Caps needed to desperately restore their innings at 7-106.
Joshua Walmsley (68 off 92) and Ben May (40 off 51) put together a cautious 82-run stand to provide resistance before Fraser rattled May's stumps. The firebrand quick also wrecked Jakob Smith's stumps before ending the innings with an athletic run-out.
"He bowls a first-class length and got wickets early which is fantastic ... his ability to come back and bowl slower balls into the wicket and change his pace and not let the batsmen settle is something our guys will learn from," coach Andy Gower said.

Launceston's swashbuckling opener Samuel Elliston-Buckley (50 off 26) broke the back of the 208-run target as he laid into Matt Talbot to take 30 runs off the over with some exhilarating strokes. The wickets of Elliston-Buckley and Dean Thiesfield did not deter Lions captain Cameron Lynch (62 off 91) from steering his side to a five-wicket win.
"The changerooms are a really good place to be at the moment and the boys are really excited about how we're going about our cricket," Gower said.
Wynyard have stormed to their first win of the season on the back Dilan Sandagirigoda's inspired performance. Sandagirigoda (52 off 56) partnered with Gregg Sharman (52 off 71) as the Tigers reached 201 all out for their highest score of the season.
Sandagirigoda (4-37) and Damon Smith (3-37) did the damage with the ball as the Knights were all out for 189 despite a late resurgence from Graham Donaldson (49 off 51) and debutant Ryan Arnott (38 off 48).
John Hayes marked his return to the Eagles' nest in grand fashion despite Mowbray slumping to defeat against Sheffield. Hayes had been out of the Eagles' side since sustaining a broken finger against Wynyard in round 3 but his return against the Mountaineers netted five wickets.
Marc Simmonds (86* off 124) played effectively a lone hand as the Mountaineers reached a total of 8-181. Two mini-collapses which saw three wickets lost for eight runs and another of three wickets for one run ensured the Eagles endured a 52-run defeat.
Masterful knocks from Brady Yates (55 off 73) and Nick Granger (52 off 60) and later James Odgers (59 off 55) ensured Burnie reached 5-254 against Riverside.
Shaun Redman (3-20) has continued his stellar start to the season to decimate the Blues in a talismanic performance. Redman had the ball humming from the first delivery to send Blues captain Tom Garwood packing before the Black Caps' chief destroyer knocked over Matthew Kerrison.
Thomas Poke (2-34) was the perfect foil as he nabbed the wickets either side of Redman dismissing Jack Manix-Geeves. Despite Patrick Mackrell's best efforts with 75 off 83, the Blues were consigned to a 113-run defeat.

An all-round effort and a devastating spell from Kieren Hume maintained Westbury's unbeaten start to the season as they overcame Devonport by 121-runs.
Hume (4-12) was remarkable as the spinner claimed the key scalps of Tyler Dell (19 off 18) and Eli Sheean (20 off 71) in succession to stunt the Orions' run-chase early before they stumbled to defeat.
Earlier, a strong foundation from Matthew Battle (44 off 68) and Nathan Parkin (39 off 69) spurred the Shamrocks onto a monsterous innings total. The platform enabled the late-order trifecta of Joel Lloyd (39 off 46), Deepak Singh (37 off 33) and Liam Ryan (28 off 20) to reach 8-251.
"[Hume's] bowling with great rhythm at the moment and he's extended the range of balls he can bowl and mixing them up really well," Westbury captain Daniel Murfet said.
"We're probably yet to play our best cricket which is actually a big positive that we've still got things to work on and we're undefeated."
