Split .wav file into equal time segments

Aim: write a code that will split a 1800 second long audio file into separate 60 second files.

I have this so far which creates a series of files consisting of the first 60, 120, 180 (etc.) seconds of the original .wav file. Am I missing something obvious or just approaching this in the wrong way?

for k = 1:60:1800
    
    samples = [1, k*fs];
    
    clear y fs;
    
    [y, fs] = audioread(wavfile, samples);
       
    filename = sprintf('VAALCO01-%d.wav', k);
    
    audiowrite(filename,y,fs);
    
end

Use the Signal Processing Toolbox buffer function.
