The duo had been trialists with the club over the course of pre-season and have now agreed deals.
Nyadzayo will be dual registered with Wroxham for the upcoming season and will be able to play in games for both clubs while Westlake has signed, subject to international clearance.
Ady Gallagher on Westlake:
"It's good to have him. He's a young lad who's got experience of playing professionally in Cyrpus and came over on trial at his own expense with the view of gaining a contract at a professional club. He's acquitted himself really well and has adjusted nicely to English football and we're happy to add him to the squad and feel he will be a really good addition."
"It's down to Cruise now, we've had him before in our Conference season when he played a few games for us then. He did very well against Waveney last week and has matured from when he was here before. We know what he can do, in one memorable game away to Stockport he came off the bench and put in an excellent performance in a 2-0 win for us and we can see he's developed since then as well. He's probably had too many clubs over the last two or three years and I think he needs to settle in one place. He knows us, he knows what is expected of him at this club. I'm really looking forward to seeing him develop even further."
The club would like to thank Tom and Ross at Wroxham FC for allowing Cruise to link up with Lowestoft and will be added to the playing squad for the upcoming season. Their co-operation is really appreciated.
