This is a good ol' double displacement reaction.  First, exchange partners:
 
    exchange   
 |               |
AX     +     BY    ––�?gt;    BX    +    AY
 
 
So, exchange the cations:
 
     exchange     
 |                  |
NaOH    +    NiCl2    ––�?gt;    NiOH    +    NaCl2
 
Then fix the formulas:
 
NaOH    +    NiCl2    ––�?gt;    Ni(OH)2    +    NaCl
 
Now balance:
 
2 NaOH    +    NiCl2    ––�?gt;    Ni(OH)2    +    2 NaCl
 
And then add the physical states:
 
2 NaOH (aq)    +    NiCl2 (aq)    ––�?gt;    Ni(OH)2 (s)   +     2 NaCl (aq)
 
And you're done!
